Doctors Near You for Tachycardia in Mujibnagar

Tachycardia is a condition where the heart beats faster than normal, generally defined as a resting heart rate exceeding 100 beats per minute in adults. This rapid heart rate can be persistent or occur in episodes and can arise from a variety of underlying causes. Tachycardia can be classified into different types based on its origin and nature, including supraventricular tachycardia (SVT), which originates above the ventricles, and ventricular tachycardia (VT), which originates in the ventricles. Sinus tachycardia is another type, characterized by a rapid but regular heartbeat originating from the heart's natural pacemaker, the sinus node. The causes of tachycardia are diverse. Physiologically, it can result from conditions such as physical exertion, emotional stress, fever, or the use of stimulants like caffeine or nicotine. Pathologically, tachycardia may be associated with underlying health issues. Conditions like heart disease, including ischemic heart disease or cardiomyopathy, can lead to VT. Other factors include electrolyte imbalances, hyperthyroidism, anemia, or dehydration. In some cases, tachycardia is linked to structural abnormalities in the heart or conditions that affect the heart's electrical system, such as atrial fibrillation or atrial flutter. Symptoms of tachycardia vary and can include palpitations, dizziness, shortness of breath, chest pain, and fatigue. In severe cases, tachycardia can result in complications like heart failure, fainting, or even sudden cardiac arrest. Treatment for tachycardia depends on its type, cause, and severity. For cases linked to physiological factors, managing stress, reducing stimulant intake, and addressing any underlying conditions may be sufficient. Pathological tachycardia may require medications to control heart rate or rhythm, such as beta-blockers or antiarrhythmics. In more severe cases, procedures like catheter ablation, cardioversion, or implantation of a pacemaker or defibrillator might be necessary. Accurate diagnosis through medical history, physical examination, and diagnostic tests like electrocardiograms is essential for effective treatment and management.
