How Do Palpitations Affect People With Existing Heart Failure or Valve Disease? 

For individuals living with heart failure or heart valve disease, the heart is already working under increased physical and metabolic strain. In these conditions, heart palpitations or ectopic beats sensations of a ‘skipped’ or ‘racing’ heart are not merely an annoyance; they can be a significant clinical indicator of how the heart is coping. The heart’s electrical system and its physical structure are deeply interconnected. When the heart muscle is weakened or when valves do not open and close correctly, the resulting physical changes can disrupt the smooth flow of electrical signals. This article explores how palpitations affect those with existing structural heart issues and explains why maintaining electrical stability is a vital part of managing heart failure and valve disease. 

What We’ll Discuss in This Article 

• The clinical impact of extra beats on hearts with reduced pumping power 

• Why heart failure and valve disease make the heart’s electrical system unstable 

• The relationship between ‘ectopic burden’ and worsening heart failure symptoms 

• Understanding how valve leaks or narrowing can trigger Atrial Fibrillation (AFib) 

• The importance of medication management in protecting structural heart health 

• Identifying ‘red flag’ symptoms that require immediate clinical intervention 

• Emergency guidance for severe cardiovascular symptoms 

The Impact of Palpitations in People With Heart Failure or Valve Conditions 

Palpitations affect people with heart failure or valve disease more significantly because their hearts have less ‘reserve’ to handle irregular rhythms. Extra or rapid beats can reduce the heart’s pumping efficiency, potentially leading to increased breathlessness, fluid retention, or a sudden worsening of heart failure symptoms. In the UK, clinicians view frequent palpitations in these patients as a signal that the heart may be under excessive strain or that a more sustained arrhythmia, such as Atrial Fibrillation, is developing. Unlike in a healthy heart, where flutters are often benign, palpitations in a compromised heart require close clinical monitoring to prevent further weakening of the heart muscle. 

In clinical practice, the focus is on maintaining ‘sinus rhythm’ the heart’s natural, steady beat. For someone with a weakened heart, every beat matters for circulating oxygenated blood; therefore, frequent electrical ‘misfires’ can directly impact their daily energy levels and long-term stability. 

The Impact of Structural Changes on Electricity 

Structural heart issues physically alter the pathways that electrical signals must travel, creating a more ‘irritable’ environment. 

• Chamber Stretching: In heart failure or valve regurgitation (leaking), the heart chambers often enlarge. This stretching of the muscle tissue creates ‘micro-scars’ that can trigger rogue electrical signals. 

• Pressure Overload: Valve stenosis (narrowing) forces the heart to pump against higher pressure. This extra work makes the heart muscle cells more sensitive to adrenaline and electrical misfires. 

• Reduced Pumping Time: Rapid or irregular palpitations (tachycardia) shorten the time the heart has to fill with blood between beats. In a failing heart, this can lead to a sudden drop in blood pressure. 

• Fibrosis: Chronic heart disease leads to fibrosis (scarring) within the heart’s ‘wiring’, which can cause electrical signals to take detours, leading to palpitations or sustained arrhythmias. 

Causes: The Cycle of Heart Failure and Palpitations 

Heart failure and irregular rhythms often form a ‘vicious cycle’ where one condition makes the other more difficult to manage. 

When the heart is in failure, the body releases more stress hormones like norepinephrine to help the heart pump harder. However, these hormones also directly irritate the heart’s electrical system, making ectopic beats and racing rhythms much more likely. This is why medications like beta-blockers are so essential; they not only help the heart pump more efficiently but also shield the heart from the hormones that trigger palpitations. In valve disease, the constant turbulence of blood flowing through a narrowed or leaky valve can physically irritate the lining of the heart, further contributing to electrical instability. 

Triggers: Factors That Worsen Symptoms 

Patients with heart failure or valve disease must be particularly vigilant about triggers that an otherwise healthy heart might tolerate. 

Factor	Why It Is Riskier	Clinical Suggestion
High Salt Intake	Increases fluid retention and heart chamber stretch.	Strictly follow the UK low-salt guidance (<6g/day).
Electrolyte Shifts	Diuretics (water tablets) can lower potassium levels.	Ensure regular blood tests to monitor mineral balance.
Anxiety / Stress	Rapidly increases the heart’s oxygen demand.	Use relaxation techniques to avoid adrenaline surges.
Caffeine	Can trigger ‘runs’ of tachycardia in a sensitive heart.	Switch to decaffeinated versions or avoid completely.
Infection	Fever makes a compromised heart beat much faster.	Seek medical advice early for respiratory or urinary infections.

Differentiation: When Is a Flutter a Warning Sign? 

In patients with structural heart disease, it is vital to distinguish between occasional skips and signs of clinical decline. 

Likely Stable (Discuss at Routine Review): 

• Occasional ‘thumps’ or ‘skips’ that feel familiar. 

• No new or worsening breathlessness. 

• No increased swelling in the ankles or legs. 

• You are still able to perform your usual daily activities. 

Requires Urgent Clinical Review: 

• A sudden increase in the frequency or intensity of palpitations. 

• New or worsening breathlessness, especially when lying flat at night. 

• A feeling of chaotic racing (suggestive of AFib) that won’t stop. 

• Significant new swelling in the ankles, legs, or abdomen. 

• Feeling faint, lightheaded, or experiencing chest pressure during palpitations. 

Conclusion 

For individuals with heart failure or valve disease, heart palpitations are a clinical priority that reflects the heart’s underlying electrical and structural health. Because a compromised heart relies on a steady, efficient rhythm to maintain circulation, frequent ‘misfires’ can lead to a decrease in pumping power and a worsening of overall symptoms. By working closely with a cardiologist or heart failure nurse, patients can manage these flutters through a combination of tailored medication, electrolyte monitoring, and lifestyle adjustments. Understanding the link between heart structure and rhythm empowers patients to recognise early warning signs, ensuring they receive the necessary clinical support to keep their heart stable and protected within the NHS framework. 

If you experience severe, sudden, or worsening symptoms, such as crushing chest pain, fainting (loss of consciousness), or severe breathlessness, call 999 immediately.
