It feels awful and you wonder if something is wrong with your heart. There are actually many different reasons for this. When it feels like your heart skips a beat or starts to beat differently, this is called a palpitation or arrhythmia.
Some arrhythmias are a temporary adjustment of the heartbeat.
Other causes are more serious. The heart is a fascinating organ. It sustains our life, yet we often take it for granted because it beats automatically. Blood flows throughout the body in a cycle. When blood leaves the right side of the heart, it travels to the lungs.
