How do I pace myself so I do not get too breathless or exhausted? 

Fatigue and breathlessness are the two most common challenges for anyone living with heart failure. Because your heart pump is less efficient, your muscles receive oxygen at a slower rate, meaning they tire much faster than they used to. Learning to pace yourself is a skill, it is not about doing less, but about doing things differently to ensure you have enough energy for the activities that matter most. In the UK, this approach is often taught in cardiac rehabilitation. By applying specific energy-saving techniques, you can maintain your independence and reduce the frequency of crashes where you feel completely wiped out for days.

The 3 Ps of Pacing 

Occupational therapists and heart failure specialists often recommend a structured framework called the 3 Ps to help manage your daily energy. 

1. Prioritising 

You cannot do everything in one day. You must choose what is most important to you. 

• The Question: Does this task need to be done today, or can it wait? 

• Action: Identify the one or two tasks that are essential, such as making a fresh meal or attending an appointment, and let the rest go. 

2. Planning 

Spontaneous activity is often the most exhausting. 

• The Strategy: Spread heavy tasks throughout the week. If you plan to go for a walk on Tuesday, don’t plan to do the laundry on the same day. 

• Preparation: Set up your environment so everything is within reach. For example, sit on a stool while preparing vegetables to save the energy used by standing. 

3. Pacing 

This is the art of ‘slow and steady’. 

• The Strategy: Break large tasks into smaller, chunks. Instead of cleaning the whole kitchen, clean one counter, sit down for ten minutes, and then do the next. 

• The Rule: Never wait until you are exhausted to rest. Rest before you feel tired to keep your energy tank from hitting zero. 

Monitoring Your Exertion: The Borg Scale 

To pace yourself accurately, you need a way to measure how hard you are working. We use the Borg RPE (Rated Perceived Exertion) Scale. 

Score	Feeling	Noble Advice
0–2	Very Easy	You can sing or talk easily.
3–4	Moderate	Breathing is deeper; you can talk but not sing. This is the goal.
5–6	Hard	Talking is difficult; you need to stop soon.
7–10	Very Hard	Gasping for air; stop immediately.

Practical Pacing Tips for Daily Life 

Small changes in how you move can lead to a saving in your total daily energy. 

• Pursed Lip Breathing: When lifting an object or climbing a stair, breathe out through pursed lips (as if blowing out a candle).² This keeps the pressure in your airways open and prevents the feeling of panic breathlessness. 

• Use Equipment: If your home has stairs, use a perch stool in the kitchen or a shower chair. These are tools that significantly reduce the heart’s workload. 

• The ‘Talk Test’: If you cannot speak a full sentence while performing an activity, you are moving too fast. Slow your pace until you can talk comfortably. 

Restorative Rest vs. Inactivity 

Pacing does not mean staying in bed all day. Total inactivity causes your muscles to weaken (deconditioning), which actually makes heart failure symptoms worse.³ 

• Active Rest: Sit in a comfortable chair with your feet up. This helps the heart by making it easier for blood to return from your legs. 

• The Balance: Aim for short periods of activity followed by short periods of rest. This keeps the ‘engine’ running without overheating it. 

According to the British Heart Foundation, learning to listen to your body’s early warning signs is the most noble way to prevent severe exhaustion. 

Conclusion 

Pacing is a essential strategy for living well with heart failure. By prioritising your most important tasks, planning your week to avoid energy peaks, and monitoring your exertion with the Borg Scale, you can reclaim control over your life. Pacing is not a sign of weakness; it is a sign of intelligence and self-awareness. It allows you to protect your heart muscle while still engaging in the activities that bring you joy and purpose. Remember, the goal is to finish the day with a little energy left in the tank, rather than running on empty. 

Emergency Guidance 

If your breathlessness does not improve with rest, or if you feel a sudden, sharp exhaustion accompanied by chest pain or a cold sweat, call 999 immediately. This is not simple fatigue; it is a warning sign of acute cardiac distress.
