A Comprehensive Analysis of Premature Contractions and Heart Failure: Identification, Prevention, and Symptom Guidelines

How to Determine if Premature Contractions Occur: If you feel a sudden "thump" in your heart, you can be sure that premature contractions may have occurred. But if you only experience chest tightness or weakness, how can you differentiate it from chest tightness and weakness caused by exertion? Dr. Zhou teaches you three methods.

1. Use an electronic blood pressure monitor. Many patients have blood pressure monitors at home. The screen displays systolic pressure, diastolic pressure, and heart rate. Some blood pressure monitors will automatically alarm when premature contractions occur, indicating that the heart has experienced premature contractions.

2. Self-monitor your pulse. Dr. Zhou often advises patients to learn to measure their own pulse. You can place your left hand on top of your right hand, or your right hand on top of your left hand, to measure it. Practice feeling your pulse frequently. After a period of time, you will have the ability to self-monitor your heart rhythm. If you find that your pulse suddenly beats prematurely, or beats at long intervals, this is very likely a premature contraction.

3. Have an electrocardiogram (ECG) or Holter monitoring.

If you experience frequent palpitations or discomfort, you should see a doctor for an ECG or Holter monitoring to confirm the diagnosis.

How to prevent and treat premature contractions:

1. Drug therapy: Treatment of premature contractions requires differentiation between atrial and ventricular premature contractions.

For atrial premature contractions, beta-blockers such as metoprolol and bisoprolol can be used; for ventricular premature contractions, propafenone, amiodarone, or traditional Chinese medicine such as Shengsong Yangxin capsules can be used. It should be noted that propafenone and amiodarone should not be taken long-term, especially amiodarone, as long-term use can lead to pulmonary fibrosis and retinopathy. Beta-blockers and Shengsong Yangxin capsules can be taken long-term, but beta-blockers are contraindicated in patients with a heart rate <60 bpm or a history of asthma. Shengsong Yangxin capsules have a bidirectional regulatory effect and can be used in patients with both fast and slow heart rates (all medications should be used under the guidance of a doctor).

2. Radiofrequency ablation: If premature ventricular contractions (PVCs) occur frequently and are not well controlled with medication, patients can choose minimally invasive radiofrequency ablation.

3. Diet: Potassium ions have a stabilizing effect on heart rhythm. Vegetables such as potatoes, broccoli, cabbage, spinach, and carrots are rich in potassium ions. Long-term consumption can stabilize heart rhythm and reduce the probability of premature contractions. It is important to note that diet only reduces the probability of premature contractions and makes the heart stronger; the above foods cannot replace medication for premature contractions.

Heart Failure:

Clinically, patients often ask if feeling chest tightness after activity or shortness of breath while sitting indicates heart failure. In fact, chest tightness after activity in heart disease patients is not always heart failure. Sometimes it is an angina attack, and sometimes it is a manifestation of neurological dysfunction caused by excessive stress. So, what are the symptoms of heart failure?

Symptom 1: Exertional dyspnea: A typical symptom of heart failure in heart disease patients is exertional dyspnea. For example, if you normally walk 100 meters without discomfort, shortness of breath, or palpitations, but recently experience shortness of breath or rapid heartbeat after only 50 meters, indicating a significant decline in activity level, this may suggest heart failure.

Symptom 2: Paroxysmal nocturnal dyspnea: Heart disease patients may experience a period of time where they are asymptomatic during the day, but suddenly experience shortness of breath or wake up gasping for air at night. Sometimes they may cough up very little clear phlegm and need to sit up to feel comfortable; or recently they may need to elevate their head with pillows to feel comfortable while sleeping. These are all typical symptoms of heart failure. If you experience these symptoms, seek medical attention as soon as possible for early diagnosis and treatment.

Symptom 3: Loss of appetite: When right ventricular function is impaired in the elderly, it can manifest as gastrointestinal congestion, causing indigestion and loss of appetite. If a heart patient has recently experienced fatigue, loss of appetite, and difficulty eating, it is highly likely that they have developed heart failure and should seek medical attention promptly.

Symptom Four: Bilateral Lower Limb Edema: If a heart patient develops pitting edema in both lower limbs, with symptoms milder in the morning and more severe in the evening, it is highly likely that they have heart failure and should undergo relevant examinations and diagnosis at a hospital.

In summary, if a heart patient experiences the above symptoms, it is highly likely that they have developed heart failure and should undergo examinations such as echocardiography and chest X-ray to confirm the diagnosis. They should not assume that they can simply tough it out, as this could delay proper medical attention.
