A healthy heart has a regular rhythm that consists of a synchronized pattern that is consistent. The lower and upper chambers of your heart work together to make this pattern which consists of a beat, then a pause, then another beat. People who suffer from bigeminy are missing the correct pause following each beat. Specifically, the beat following the pause comes much earlier than it should which can result in an inconsistent pattern of long and short beats.
When the early beats originate from the upper chambers of the heart, they are called premature atrial contractions. If the early beats originate from the lower chambers of the heart, they are called premature ventricular contractions.
The upper portion of your heart is dedicated to the exchange of carbon dioxide and oxygen in your lungs while the lower portion is dedicated to circulating the freshly oxygenated blood all over your body.
1. Skipped Heartbeat
Not many people actively pay attention to their heartbeat. After all, it is a sensation that has been with you before birth and followed you through your whole life. Bigeminy affects the way your heart beats and disrupts its usual pattern, but the change is often so subtle that it is hard to notice premature contractions are happening. If you are one of the few who is actively aware of their heartbeat, you may notice when it skips. It may seem as if it has skipped a full beat when in actuality the pause is simply shorter or longer than it should have been.
A skipped heartbeat is easier to detect when one is at a period of rest, or when a person has participated in an activity that increased the heartbeat tremendously. One of the key symptoms of bigeminy is a skipped heartbeat, though a skipped heartbeat does not always mean a person is suffering from bigeminy.
