1 The resting heart rate for a healthy adult is between 60 and 100 beats/minute. 2  Bradycardia (resting heart rates slower than 60 beats/minute) does not always cause low blood pressure. 3  In fact, some highly trained athletes can have resting heart rates in the 40s and 50s (beats per minute) without any symptoms.he most common example of tachycardia causing low blood pressure is atrial fibrillation. Atrial fibrillation is a disorder of the heart characterized by rapid and irregular electrical discharges from the muscle of the heart causing the ventricles to contract irregularly and (usually) rapidly.
