Tachi

Tachycardia is a medical condition characterized by a heart rate that exceeds the normal resting rate. Generally, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. The heart rate is controlled by the electrical system of the heart and this is responsible for the coordination of the heart beat. This condition can disrupt normal heart function and increase the risk of stroke, sudden cardiac arrest, or death.

Causes

Tachycardia can be caused by several factors, including heart disease, high blood pressure, and lung diseases. Other causes can include hyperthyroidism, heavy alcohol use, smoking, and the use of certain medications and supplements.

Symptoms

Symptoms of tachycardia include dizziness, shortness of breath, lightheadedness, rapid pulse rate, heart palpitations, and chest pain. However, some people with tachycardia may not experience any symptoms or complications.

Diagnosis

Tachycardia can be diagnosed through a physical examination, blood tests, electrocardiogram (ECG), Holter monitoring, event recording, and echocardiogram.

Treatment

Treatment for tachycardia aims to address the underlying cause, slow the fast heart rate, prevent future episodes, and reduce complications. Treatment options can include vagal maneuvers, medications, cardioversion, catheter ablation, surgery, and implanted devices like pacemakers or implantable cardioverter defibrillators (ICDs).

Prevention

Prevention strategies for tachycardia include maintaining a healthy weight, regular exercise, quitting smoking, controlling high blood pressure, limiting caffeine and alcohol, and reducing stress.
