How to Discuss Exercise Intensity in Cardiac Rehab

During cardiac rehab, you may repeatedly ask yourself, "Am I pushing too hard right now?" or "The heart rate on my device changed. Should I stop?" You can bring up these questions during your rehab session. You do not need to wait until the session is over.

This guide helps you practice describing how you feel during activity, recording questions, and confirming plans with rehab staff. It does not provide exercise intensity levels, heart rate targets, or criteria for increasing activity that apply to everyone, and it cannot replace a doctor's evaluation or your individual rehab plan. Follow your medical team's guidance on your activity limits, movements to avoid, and when to stop.

This illustration helps explain the communication topics. It is not an individual exercise prescription or clinical evidence.

Confirm the Session's Goals Using Your Approved Rehab Plan

Before you begin, ask rehab staff to clarify the session's plan: which activities you will do, in what order, how to report how you feel, and when to pause. Do not assume, based only on your last session, that you can follow the same routine or increase your activity this time.

You can ask, "Are we following the original plan today, or are there changes? When should I tell you how I feel during the activity?" If any terms in the plan are hard to understand, ask staff to explain them using specific movements or demonstrate them in person.

Tell rehab staff about recent changes in your health, any discomfort you currently have, and any medication changes. They can then determine whether these affect the day's plan. You do not need to decide whether a change is "serious enough" before mentioning it.

Before starting, try to confirm the following:

• The approved activities and limits for this session.

• The method your team wants you to use to report exercise intensity.

• Activities you need to avoid and the specific conditions for pausing or stopping.

• Whom to tell if a problem occurs and how to get help on site.

If any of these points are unclear, ask staff to explain them first. Do not fill in the gaps yourself.

Ask Rehab Staff to Show You How to Describe Exertion and Breathing

"I feel a little tired" is a starting point, but you can be more specific. Describe where you feel the effort, how your breathing has changed, and whether the feeling began when you started the activity or developed gradually.

For example: "My legs are working harder, and I'm breathing faster than when I started. Could you check on me?" This reports your experience without making your own judgment about whether the intensity is safe.

If your team uses a perceived exertion scale, ask them to explain what it means, how to choose a description, and how to report your exertion for this session's plan. Do not simply use a scoring range you found online or push yourself to continue just to reach a particular score.

You can practice a complete statement during the session: first say what you are doing, then describe how your body feels, and finally say what you need. "I'm doing the walking activity in my plan, and talking feels harder now than it did a moment ago. Please help me check whether I need an adjustment." Rehab staff can ask follow-up questions based on what is happening.

You do not need to use medical terms. If you cannot tell whether you are feeling fatigue, anxiety, or another kind of discomfort, say, "I'm not sure," and then describe what you actually feel.

Why Device Heart Rate Readings Need Personal Context

The heart rate shown on a device provides a reading to discuss, but this guide cannot use it to determine whether you are overexerting yourself. Rehab staff need to interpret what the number means, whether the reading is reliable, and what action to take in the context of your individual plan and the situation.

Instead of repeatedly checking general heart rate formulas, ask, "Does my plan require heart rate monitoring? If so, what range should I use? What should I do if the reading does not match how I feel?"

If a reading changes suddenly, report what you were doing, what the device showed, and how you felt. For example: "The number on my device suddenly changed during the activity. I don't feel any obvious discomfort right now, but I need you to check it." Do not assume the change means the device is malfunctioning or that a particular number means something is wrong with your body.

Likewise, do not use "the number looks normal" as a reason to ignore discomfort. Whether you continue should depend on your individual stopping instructions and the judgment of the professionals on site, rather than the screen alone.

Record the Activity, What Happened, and How You Felt Together

The purpose of keeping notes is to help rehab staff understand what happened, rather than to grade yourself on whether a session was "successful." Recording the activity's context alongside changes in how you felt makes later conversations more useful than writing down only a heart rate or the word "tired."

You can use a short checklist:

• Activity: Which activity in your plan you were doing.

• Timing: Whether the change occurred at the start, during, or after the activity. If you are unsure of the time, note roughly when it happened.

• Physical sensations: The specific location, what the sensation felt like, and whether it changed gradually.

• Device information: If your team asks you to record it, note the reading and the device used.

• Response during the session: Whether you reported it, what instructions staff gave you, and how you felt afterward.

• Questions to clarify: What you need your team to explain next time.

Leave anything you do not remember blank or mark it "not sure." Do not fill in details just to make the record complete. Taking notes should never delay reporting discomfort or seeking help.

How to Report Discomfort and Follow Instructions to Stop Activity

If you develop new discomfort or notice a clear change in how you feel, tell rehab staff promptly and pause or stop according to the instructions you confirmed beforehand. Do not put "finishing the remaining time" ahead of getting help or try to test your symptoms by increasing or decreasing the intensity yourself.

Start with the most important information: "I don't feel well right now. I need help." Then, if possible, explain where the discomfort is, when it began, and what you were doing at the time. If speaking in full sentences is difficult, signal for staff to come over. You do not need to wait until you have worked out how to describe it.

If you experience warning signs such as chest pain or pressure, severe difficulty breathing, fainting, or altered awareness, stop activity immediately and seek emergency help on site. If you are somewhere without medical staff, contact local emergency services promptly. Do not wait for a device alarm, continue exercising alone, or drive yourself to get medical care.

Even after the discomfort improves, the professional responsible for your care should determine the next steps and whether you can resume activity. Temporary relief is not permission to continue. Follow your established individual medical instructions for medications and emergency care. Do not add medication or change doses yourself.

Completing One Session Is Not a Basis for Increasing Activity on Your Own

Completing a session only means that the activity has ended. It cannot, by itself, determine whether you should increase your speed, duration, resistance, or repetitions next time. "I had no obvious discomfort today" and "I have approval to increase my activity" are two separate points that need to be confirmed.

If the session felt relatively easy, tell rehab staff: "I felt like I still had some energy left after finishing today. Should we make an adjustment next time? If so, exactly what should change?" Similarly, if you remain tense because you worry about overexertion, ask your team to explain the activity goals and stopping conditions again.

Until you receive clear instructions, keep following the plan you have already confirmed. Do not test your limits by doing a little extra or copy another participant's pace or session length.

Review Your Notes With Rehab Staff and Confirm the Next Session's Intensity

Your discussion after a session can focus on three questions: what you actually did, which sensations need an explanation, and exactly what the plan is for next time. Discussing uncertain details in your notes is more appropriate than guessing what they mean yourself.

You might say, "About halfway through this activity, I noticed I was breathing faster than at the start, and I told the staff on site. Should we keep the same plan next time? What should I do if I feel that way again?"

Before the conversation ends, repeat the plan in your own words: "My understanding is that next time I'll follow the activities you've confirmed and report how I feel at the agreed times. If any of the stopping conditions you described occur, I'll stop and ask for help. Is that right?" If anything is still unclear, ask staff for enough detail to put the instructions into practice.

During rehab, your role is to report your feelings and questions honestly. Your medical team's role is to assess your individual situation and develop your plan. You do not need to draw conclusions on your own from one number or one session. Clearly communicating information and confirming the next step are the focus of this feedback practice.

Medical and Health Frequently Asked Questions

1. When someone with cerebrovascular disease has difficulty expressing themselves, how can they participate in conversations at Heart Alliance's cardiovascular clinic?

When scheduling an appointment at Heart Alliance, explain the patient's specific communication needs and ask whether a longer appointment is available. Prepare written words, pictures, or simple choices based on the patient's preferences. Discuss one question at a time and allow plenty of time for a response. Family members should distinguish what the patient communicates from their own observations, rather than guessing the patient's feelings or thoughts for them. The care or rehab team can help develop specific communication support strategies.

2. What information should I prepare before visiting Heart Alliance's cardiology department for palpitations or sensations that feel like premature beats?

Record when each episode begins, how long it lasts, how often it happens, what you were doing, and how you were feeling emotionally. Also note whether you have chest pain, shortness of breath, dizziness, or fainting at the same time. Gather your previous test results and make a list of your medical history, family medical history, and all medications and supplements you currently take. A doctor generally needs an in-person evaluation and any necessary tests to determine the cause. You cannot determine whether you are having premature beats based on the sensation alone.
