What are other names for Ectopic heartbeat?
What are Ectopic Heartbeats? Commonly known as PVC’s, ectopic heartbeats are heartbeats that have their origins in the ventricles of the heart rather than from the sinoatrial (SA) node. PVCs are termed premature because they are triggered before the normal heartbeat occurs. How is the heart supposed to work? The heart is built like the old stereotypical English house – two up, two down. The two upstairs chambers are called the Atria (plural of atrium). The two downstairs chambers are called the ventricles. The two upper atria receive blood from the veins and lungs and deliver it to the lower ventricles. The ventricles accept blood from the atria and deliver it to the lungs and to the rest of the body. The low-oxygen venous (from the veins) blood arrives in the right atrium and is then passed to the right ventricle. From there it is pumped to the lungs for enrichment with oxygen. From the lungs, the blood enters the left atrium and is passed to the left ventricle where it is pumped back
