I49.1: Atrial premature depolarization
You are having additional heartbeats.
Your heart is beating irregularly. You are sometimes having additional heartbeats that do not occur with the normal rhythm.
The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition. The heart’s electrical activity originates in the right atrium. The heart’s electrical activity triggers the heartbeat. The activity then first spreads in the two atria. The activity then flows via a sort of cable from the atria to the ventricles.
You keep getting additional heartbeats in your heart’s atria.
