Arrythmia

  Arrythmia  An arrhythmia is a disturbance of the heart's rhythm. An arrhythmia may result in a fast or slow heartbeat and/or produce an even or uneven rhythm. Two common arrhythmias arising from the atria are paroxysmal atrial tachycardia and atrial fibrillation. PAT often occurs in young, healthy individuals without heart disease. The heart beats at a rate of 150 to 250 beats per minute (BPM) rather than the normal 60 to 100 BPM. Despite the fast beating, individuals usually feel fine because they are young and healthy.

Signs and symptoms: The most common symptom of arrhythmia is an abnormal awareness of heartbeat, called palpitations. some asymptomatic arrhythmias are associated with adverse events include a higher risk of blood clotting within the heart and a higher risk of insufficient blood being transported to the heart because of weak heartbeat.

 Prevalence: Arrhythmias are common and occur throughout the population. The prevalence of atrial and ventricular arrhythmias increases with age, even when there's no clear sign of heart disease. During a 24-hour period, about one-fifth of healthy adults are likely to have frequent or multiple types of premature ventricular beats and as many as 1.5 million people living in poland with AF
