overview
Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of the two lower pumping chambers (ventricles) of your heart. These extra beats disrupt your normal heartbeat and sometimes cause you to feel a beat or a skipped beat in your chest. Ventricular premature contraction Treatment in Khammam
Premature ventricular contractions are common – they happen in many people. They are also called:
- Premature ventricular complexes
- Premature ventricular beats
- Ventricular extrasystoles
symptoms
Premature ventricular contractions often cause little or no symptoms. But you might feel a strange feeling in your chest, such as:
- Floating
- Hit or jump
- Skipped beats or missed beats
- Increased awareness of your heartbeat
The reasons
- Normal heartbeat.
- Normal HeartbeatOpen popup dialog.
- Your heart is made up of four chambers – two upper chambers (atria) and two lower chambers (ventricles). Your heart’s rhythm is usually controlled by the sinoatrial (SA) node – or sinus node – an area of specialized cells in the right atrium. Ventricular premature contraction Treatment in Khammam
This natural stimulator creates the electrical impulses that trigger the normal heartbeat. Electrical impulses travel from the sinus node through the atria to the ventricles, causing them to contract and pump blood to your lungs and body.
Risk factors
The following can increase your risk for PVC:
- Caffeine, tobacco, alcohol and illegal drugs
- Exercise – when you have certain types of PVC
- High blood pressure (hypertension)
- fear
Complications
Frequent PVCs or some types of PVCs can increase the risk of developing problems with the heart rhythm (arrhythmias) or weakening of the heart muscle (cardiomyopathy).
In rare cases, frequent premature contractions associated with heart disease can lead to chaotic and dangerous heart rhythms and possibly sudden cardiac death.
