Pacemakers are often used for slow heart rates. [6] Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. [6] Those who have severe symptoms from an arrhythmia or are medically unstable may receive urgent treatment with a controlled electric shock in the form of cardioversion or ...
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11] [12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4]
In this condition the normal electrical pulses coming from the sinoatrial node are overwhelmed by disorganized electrical impulses usually originating in the roots of the pulmonary veins, leading to irregular conduction of impulses to the ventricles which generate the heartbeat.
Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat. Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat, or normal heartbeat. The two beats are figuratively similar to two twins (hence bi-+ gemini).
A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...
Palpitations occur when a person becomes aware of their heartbeat. The heartbeat may feel hard, fast, or uneven in their chest. [1] [2] Symptoms include a very fast or irregular heartbeat. Palpitations are a sensory symptom. [1] They are often described as a skipped beat, a rapid flutter, or a pounding in the chest or neck. [1] [2]
Ventricular fibrillation (V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1]
People with TIC most often present with symptoms of congestive heart failure and/or symptoms related to their irregular heart rhythm. [1] Symptoms of congestive heart failure can include shortness of breath, ankle swelling, fatigue, and weight gain. [2] Symptoms of an irregular heart rhythm can include palpitations and chest discomfort. [2]
