This causes the atrium to flutter and twitch. In this, the ECG identifies a rate of heartbeat less than 60 beats per minute.Ītrial fibrillation occurs when the sinus node sends irregular impulses to the atrium and the upper valves pump blood irregularly or without any orientation to each other or to the ventricles. For an average adult, anything above 100 beats per minute can be considered as Tachycardia.īradycardia occurs when the heart beats too slow. Tachycardia is a form of an Arrhythmia that occurs when the heart is beating too fast without the patient’s participation in any excessive physical activities at that moment. On a broader spectrum, an Arrhythmia can be classified into different types depending on the irregularity presented in the electrocardiogram. These electrolytes help trigger electrical impulses through the sinusoidal artery and an electrolyte imbalance can hamper the way the signals are sent to the atrium and ventricles in the heart, causing them to pump blood irregularly. Imbalance in the amount of sodium, potassium, calcium and magnesium electrolytes in the body can be a major driving force causing irregular heartbeats. The thyroid glands are the hormone centres of the body and over-secretion or under-secretion of these glands can cause irregular heartbeats. Congenital conditions:Ĭertain conditions or deformities in the heart which is causing irregularities in the way the heart pumps blood in turn leading to an irregular heart beat. It can also increase the risk of developing coronary artery (narrowing in the arteries due to deposits of cholesterol-containing plaque). High blood pressure can cause stiffening of the walls in the ventricles and this can cause an Arrhythmia in the heart. Previous heart surgeries due to a heart attack or narrowed walls can lead to Arrhythmias, which can subsequently be a cause of an offset of irregular heartbeats. These conditions include: Coronary heart disease: However, there are a few conditions which when left undiagnosed and untreated can become life-threatening.
