♦ Ischemic cardiomyopathy: As a result of a heart attack or coronary artery disease, your heart muscle weakens causing ischemic cardiomyopathy. This is the leading cause of death from high blood pressure and can be very serious. ♦ Hypertensive Heart Disease: Diseases of the heart caused by hypertension can include heart failure, coronary artery disease, and thickening of the heart muscle. Heart attacks or myocardial infarctions occur as a result of the heart’s oxygen supply being cut off. Atrial and ventricular fibrillation cause the heart to pump inefficiently, and this can cause a heart attack if left untreated. ♦ Heart attack: Certain types of irregular heartbeat can lead to a heart attack. This leakage can cause fatal problems, including blockage of blood flow and blood flowing into your lungs. This happens when the inner layer tears or a rupture occurs in any of the smaller blood vessels that supply the aorta. ♦ Dissection of the aorta: The aorta carries blood out of your heart, and a dissection means blood is leaking outside of this blood vessel. This enlarged heart condition can develop over time or can be inherited. Dilated cardiomyopathy is the most common type, and it develops when the muscles become stretched and thin, allowing the heart chambers to expand. It can also cause an irregular heartbeat. The heart becomes weak and unable to pump blood effectively. ♦ Congestive (Dilated) Cardiomyopathy: Cardiomyopathy is a progressive disease affecting the heart muscle (myocardium). CHF can be life-threatening, so medical treatment is needed immediately. Once fluid builds up around the heart, it cannot beat efficiently, and as a result, the heart and other organs do not get the blood or oxygen supply they need. ♦ Congestive Heart Failure: This chronic and progressive condition impacts the power of your heart muscles to pump blood. With proper medical care, you can live a normal life with both conditions. This causes a faster heart rate, but the rhythm remains more stable than with atrial fibrillation. Atrial flutter occurs in the right atria more often and is caused by a single misfiring impulse. ♦ Atrial fibrillation and flutter: Atrial fibrillation is the most common type of irregular heartbeat and occurs when several electrical impulses misfire and the atrial chambers quiver uncontrollably. There are a number of more serious diseases associated with an irregular heartbeat: Imbalanced electrolytes can also cause temporary irregular heartbeats. Other causes of rapid heartbeats can also include reactions to certain medications such as amphetamines and beta-blockers. Irregular Heartbeat CausesĪn irregular heartbeat that is temporary may be caused by anxiety or stress. Some people like athletes have naturally lower heartbeats because of their great physical condition. This type usually results from disrupted electric signals between the atria and ventricles. ♦ Bradycardia: When your heartbeat is slower than 60 beats per minute, it’s referred to as Bradycardia. Tachycardia can start in either chamber or can be caused by a normal reaction to stress or excitement, or even when you get sick. ♦ Tachycardia: When your heart is beating over 100 beats per minute as compared to the normal rate of 60 beats per minute, you have tachycardia. The irregular heartbeat can originate in either the upper (atrial arrhythmia) or lower (ventricular arrhythmia) chambers of the heart. You may be able to feel that your heart is beating faster or slower, but in addition to this, an irregular heartbeat can also cause other symptoms, including:Ī heartbeat that is too fast is known as tachycardia, and one that is too slow is known as bradycardia. Since they can signal an underlying heart condition that could be more serious, it is important not to ignore them. Irregular heartbeats are known as arrhythmias or heart rhythm disorders, and they are not generally life-threatening. When anything causes disruption to the valves, nodes, or chambers in your heart and blood flow, the pattern of the heartbeat will become disrupted too. An irregular heartbeat is when your heart is beating too fast or too slow.
