What is Frequent Premature Ventricular Contractions (High PVC Burden)?

Premature ventricular contractions (PVCs) are common ectopic beats that originate from the ventricles. On 24-hour Holter monitoring, PVCs exceeding 10–15% of total heartbeats are considered 'frequent' and increase the risk of PVC-induced cardiomyopathy.

A high PVC burden can impair left ventricular function over time, leading to a reduced ejection fraction. This process is reversible — function typically recovers once the PVCs are eliminated. The origin of the PVCs (most often the right ventricular outflow tract) guides therapy.

Diagnosis is made by 24-hour Holter, echocardiography and cardiac MRI. Treatment options in symptomatic patients include beta-blockers, calcium channel blockers or antiarrhythmic drugs; catheter ablation is preferred in patients with a very high burden or established cardiomyopathy.

Symptoms

Palpitations (skipped or extra beats)
Neck pulsations
Fatigue
Dyspnea
Dizziness
Chest discomfort
Sometimes asymptomatic

Risk Factors

Structural heart disease
Caffeine and alcohol
Smoking
Stress
Electrolyte disturbances
Thyroid disease
Sleep deprivation

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Frequent or recurrent palpitations
  • Exercise intolerance
  • Unexplained fatigue
  • Syncope or presyncope
  • High PVC burden on Holter
  • Falling ejection fraction

Treatment Methods

01
Trigger avoidance (caffeine, alcohol, smoking)
02
Beta-blockers
03
Calcium channel blockers
04
Antiarrhythmic drugs (flecainide, propafenone)
05
Catheter ablation for high burden or cardiomyopathy
06
Electrolyte monitoring
07
Regular cardiology follow-up

Hypertension (High Blood Pressure)

Kardiyoloji

Hypertension is a condition in which blood pressure readings remain above 140/90 mmHg; early treatment helps prevent serious complications.

Narrowing of the coronary arteries due to atherosclerosis can cause chest pain (angina) and heart attack.

Heart Failure

Kardiyoloji

Heart failure is a chronic cardiac condition characterized by shortness of breath, leg swelling, and fatigue.

Heart Attack (Myocardial Infarction)

Kardiyoloji

A heart attack is a medical emergency; because heart muscle is lost by the minute, immediate intervention saves lives.

Atrial Fibrillation

Kardiyoloji

Atrial fibrillation is a common arrhythmia characterized by an irregular heartbeat and increased risk of stroke.

Heart Palpitations

Kardiyoloji

Palpitations are usually due to benign causes, but underlying cardiac rhythm disorders must be ruled out.

Heart Valve Diseases

Kardiyoloji

Valve stenosis or regurgitation increases the workload of the heart and, over time, can lead to heart failure.

Aortic Aneurysm

Kardiyoloji

Aortic aneurysms are often silent; early diagnosis allows treatment before rupture (a life-threatening tear).
