How does ventricular tachycardia and PVCs affect the heart?
How does ventricular tachycardia and PVCs affect the heart?
HomeArrhythmia InformationVentricular Tachycardia and PVCs. Ventricular tachycardia is a fast heart rate, anything over the normal 100 beats per minute, which starts in the lower chambers of the heart, the ventricles. It causes the ventricles to contract before they have had a chance to completely fill with blood, impairing blood flow to the body.
What is the significance of PVC heart beats?
It appears that the significance of PVC’s depends on the underlying heart. In abnormal hearts such as those withcoronary artery diseaseor heart muscle dysfunction PVC’s are known to be associated with poor outcomes. Whereas in apparently normal hearts, the significance of PVC’s is less well known and certainly thought to be of less concern.
When to see an electrophysiologist for PVC heart beats?
In very symptomatic patients or those with high PVC burden, i.e. greater than 20% referral should certainly be made to an electrophysiologist to discuss treatment options. In general even those with fairly frequent PVC’s who have had underlying heart disease ruled out can be reassured and likely have a good prognosis.
Do you feel heart palpitations when you have PVC?
Most people with PVCs have no symptoms at all. They simply don’t feel them. However, a substantial minority of people with PVCs will perceive palpitations —an unusual awareness of the heartbeat. These palpitations are often described as “skipped beats” or a “pounding heart.”

What happens to patients with a high PVC rate?
Patients with a high frequency of PVC (> 20-40% of all beats) may require more aggressive therapy independent of symptoms. There have been some reports of frequent PVCs resulting in a “tachycardia induced” cardiomyopathy, which can be reversed with successful elimination of PVCs by catheter ablation (ref 1).
When do premature ventricular contractions ( PVCs ) occur?
Premature Ventricular Contractions (PVCs) are single beats originating from the lower chambers. Any time there is more than 3 beats in succession this is defined as ventricular tachycardia. Most of the time ventricular tachycardia occurs in people with underlying heart abnormalities. Sometimes in can occur in structurally normal hearts.
What is the normal resting heart rate for ventricular tachycardia?
A normal resting heart rate is 60 to 100 beats per minute. Ventricular tachycardia starts in the heart’s lower chambers. Most patients who have ventricular tachycardia have a heart rate that is 170 beats per minute or more. Cleveland Clinic is a non-profit academic medical center.
