In a normal person, the pulse and heart rate are equal and the normal range is 60-100 beats per minute. A pulse rate of 80 beats per minute falls within the normal range. A pulse rate below 60 beats per minute is considered bradycardia; above 100 beats per minute is considered tachycardia. There are physiologic and pathologic types of bradycardia. Athletes, physically active workers, or a portion of the elderly with low activity levels are prone to bradycardia. Pathologic bradycardia is seen in hypothyroidism, or in some patients with elevated intracranial pressure and some patients with myocardial infarction. Drug-induced bradycardia includes beta-blockers among anti-hypertensive medications, such as Betalucil and Combi, as well as antiarrhythmic medications, such as ketorolac and mesylate, which can cause sinus bradycardia. When the heart rate is greater than 100 beats is referred to as tachycardia, physiologic tachycardia are sinus tachycardia, can appear after strenuous activities, tension, anxiety. Pathologic tachycardia requires electrocardiography and 24-hour ambulatory electrocardiographic monitoring to clarify the exact nature of the tachycardia, which commonly includes supraventricular tachycardia and rapid atrial fibrillation.
