What are the characteristics of premature ventricular contractions?

Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of your heart’s two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a fluttering or a skipped beat in your chest.

What is a premature ventricular contraction?

Premature ventricular contractions, or PVCs, are a type of abnormal heartbeat. Your heart has 4 chambers: 2 upper atria and 2 lower ventricles. Normally, a special group of cells start the signal for your heartbeat. These cells are in the sinoatrial (SA) node in the right atrium.

What are the three properties which are used to identify PVCs?

Signs and symptoms PVCs may be perceived as a skipped heart beat, a strong beat, palpitations, or lightheadedness. They may also cause chest pain, a faint feeling, fatigue, or hyperventilation after exercise. Symptoms may be more pronounced at times of stress.

What does premature ventricular contraction ( PVC ) mean?

A premature ventricular contraction (PVC) is a too-early heartbeat that originates in the ventricles and disrupts the heart’s normal rhythm. The pattern is a normal beat, an extra beat (the PVC), a slight pause, then a stronger-than-normal beat. The heart fills with more blood during the pause following the PVC, giving the next beat extra force.

Is there any treatment for premature ventricular contractions?

Premature Ventricular Contractions (PVCs) ECG Review. No treatment is necessary for PVCs. If symptomatic, beta-blockers or antiarrhythmic drugs can be effective. Rarely, ablation of PVCs is needed.

Where does the heartbeat come from in premature ventricular contractions?

Premature Ventricular Contractions. The heartbeat is created by an electrical signal that originates in an area of specialized cells in the heart’s upper right chamber, the right atrium. The electrical signal moves down through the heart to the atrioventricular (AV) node, a cluster of specialized cells in the center of the heart.

Can a ECG detect premature ventricular contractions?

Premature ventricular contractions (PVCs) Print. An electrocardiogram (ECG) can detect the extra beats and identify the pattern and source. Depending on the frequency and timing of your PVCs, different types of ECG testing options are available.

What can trigger PVCs?

According to the National Institutes of Health, PVCs can be caused by various triggers such as heart disease, changes in your blood potassium level, smoking, caffeine or certain medications.

What causes PVCs and PACs?

PVCs and PACs occur when electrically-active tissue in the heart decides to fire off (depolarize) before it has received the signal from the normal pacemaker of the heart, the sinus node. PACs come from one of the atria (upper chambers of the heart). PACs generate an early beat (ventricular depolarization).

What medications can cause PVCs?

You may be taking medications that cause PVC without actually being aware of it. These include anti-asthma medications (salbutamol, theophylline), nasal decongestants (pseudoephedrine), thyroxine and other sympathomimetic drugs. These substances excite the heart and make people more prone to developing PVCs.

How and when to treat PVCs?

Try taking some Tums or Rolaids until your stomach feels better and see if your PVC’s don’t go away. A word of warning about ulcers and GERD ; a common treatment for these ailments is Prilosec, which can have a long term impact on your PVC’s.
