High blood pressure means too much force is required to push the blood through your blood vessels. Several factors may cause an abnormal heart rhythm. In either case, when feeling your pulse, it may feel as though your heart pauses or skips a beat. It can occur in the atrium (premature atrial contraction) or in the ventricle (premature ventricular contraction). Premature contractionsĪ premature contraction is a beat that occurs early. It’s a serious condition that results in death if not immediately treated with defibrillation. This impairs the flow of blood from your heart and leads to cardiac arrest. Ventricular fibrillation is a life threatening arrhythmia in which the ventricles beat rapidly and erratically. medications, including certain blood pressure and antiarrythmic medications.Some athletes have slower heart rates because they’re in excellent physical condition, which isn’t usually the result of a heart problem. Bradycardia generally occurs when the electrical signals traveling from the atria to the ventricles become disrupted. If you have bradycardia, you have a slow heart rate (less than 60 bpm). In atrial flutter, your heart’s overall rhythm can be regular, but your heart rate is often fast.Ītrial flutter also increases your risk of stroke. It’s due to an abnormal circuit of electrical activity. It may occur in the left atrium as well.Ītrial flutter is a type of arrhythmia that originates in the atrium and results in rapid atrial rhythm. Atrial flutterĪn atrial flutter typically occurs in the right atrium, one of your heart’s two upper chambers. It’s the most common arrhythmia.Ītrial fibrillation, or AFib, occurs when many unstable electrical impulses misfire, causing your atria to quiver erratically.ĪFib causes your heart to beat irregularly and can increase your heart rate to 80 to 180 bpm, which is much faster than the typical 60 to 100 bpm. This disorganized heart rhythm occurs in the upper chambers of your heart. Ventricular tachycardia: Ventricular tachycardia is a very fast heart rate that occurs in the lower chambers, known as the ventricles.Supraventricular tachycardia: Supraventricular tachycardia originates in the upper chambers of your heart, known as the atria.With sinus tachycardia, your heartbeat returns to its usual rate once you get better or become calm. Sinus tachycardia: This is an increased heart rate that can occur in response to exercise, pain, dehydration, excitement, fever, or illness.Tachycardia is any resting heart rate over 100 beats per minute (bpm). For example, a typical heart beats 60 to 100 times per minute in adults.

Tachycardia means that your heart is beating too fast. The most common types of abnormal heart rhythms include: Tachycardia
