Although treatable, an irregular heart beat can be a serious medical condition, according to Healthline. Some types of irregular heart beat such as ventricular fibrillation can be deadly, claims Mayo Clinic. Ventricular fibrillation occurs when there is a rapid heart beat accompanied with erratic electrical impulses.
An irregular heart beat occurs when there is a malfunction in the electrical impulses that coordinate the heart beats, explains Mayo Clinic. This leads to irregular heart beat. It also raises or lowers the heart beat speed.
The symptoms of irregular heart beat may include a chest fluttering, tachycardia, bradycardia, breath shortness, lightheadedness, dizziness, fainting and chest pain, notes Mayo Clinic. A patient should seek immediate medical care when he experiences these symptoms.
