Tachycardia and bradycardia are two types of heart arrhythmias, which occur when the electrical signals that coordinate the hearts beats dont work properly. Tachycardia is a fast heartbeat, where the resting heart rate is greater than 100 beats per minute. Bradycardia, on the other hand, is a slow heartbeat, where the resting heart rate is less than 60 beats per minute. Both conditions can be caused by an electrical problem within the heart, which causes the sinus node (the hearts natural pacemaker) to operate improperly.
Symptoms of tachycardia and bradycardia can include fainting or passing out, heart palpitations, lightheadedness, and near-fainting. Tachy-brady syndrome is a condition where the heart rate fluctuates between beating too quickly (tachycardia) and too slowly (bradycardia) . This condition can be caused by sick sinus syndrome, a problem in the area of the heart that regulates the speed of heartbeats, or atrial fibrillation (AFib), a particular type of irregular heartbeat.
Treatment for tachycardia and bradycardia depends on the underlying cause and severity of the condition. Treatment options can include medications, procedures, and devices such as pacemakers. If you experience symptoms of tachycardia or bradycardia, it is important to seek medical attention to determine the underlying cause and appropriate treatment.
