This usually appears on an electrocardiogram (EKG) with a normal QRS complex accompanied with an inverted P wave either before, during, or after the QRS complex. This can be the result of issues with the sinoatrial node, which functions as the pacemaker, or damage to the heart as an outcome of a heart attack or heart disease. A blood pressure reading lower than 90 millimeters of mercury (mm Hg) for the top number (systolic) or 60 mm Hg for the bottom number (diastolic) is generally considered low blood pressure. However, in the case of well-trained athletes a 45 pulse may be normal as heart rates as low as 40 bpm are considered regular for those in top physical condition. They can be caused by anemia, fever or hyperthyroidism, among other reasons. A diagnosis of bradycardia in adults is based on a heart rate less than 60 BPM, although some studies use a heart rate of less than 50 BPM.

Tachycardia occurs when an abnormality in the heart produces rapid electrical signals that quicken the heart rate, which is normally about 60 to 100 beats a minute at rest. [14][15], The US Centers for Disease Control and Prevention reported in 2011 that 15.2% of adult males and 6.9% of adult females had clinically-defined bradycardia (a resting pulse rate below 60 BPM).

[5], The third, sick sinus syndrome, covers conditions that include severe sinus bradycardia, sinoatrial block, sinus arrest, and bradycardia-tachycardia syndrome (atrial fibrillation, atrial flutter, and paroxysmal supraventricular tachycardia). With SA node dysfunction (sometimes called sick sinus syndrome), there may be disordered automaticity or impaired conduction of the impulse from the SA node into the surrounding atrial tissue (an "exit block"). For some people, a slow heart rate does not cause any problems. [13] This is determined usually either by palpation or EKG. [13] Transvenous pacing may be required if the cause of the bradycardia is not rapidly reversible. I went to walk in the treadmill and my rate went from 40 to 100, walking up to 3.5 miles per hr.

[1] Bradycardia typically does not cause symptoms until the rate drops below 50 BPM. A lower resting heart rate (RHR) is a sign of quality recovery and health. [7] This is a protective mechanism for the heart, to compensate for an SA node that is no longer handling the pacemaking activity, and is one of a series of backup sites that can take over pacemaker function when the SA node fails to do so. Factors determining prognosis in 100 patients with recent onset of congestive heart failure (CHF) were evaluated. You may experience heart-related complications if your resting heart rate is 65 or 70 BPM. When your skin is injured or broken, platelets clump together and form clots to stop the bleeding. For some patients, the elevated heart rate is the only symptom. Though rare, severe thrombocytopenia can cause bleeding into the brain, which can be fatal.

For adults 18 and older, a normal resting heart rate is between 60 and 100 beats per minute (bpm), depending on the person's physical condition and age. [5], An AV-junctional rhythm, or atrioventricular nodal bradycardia, is usually caused by the absence of the electrical impulse from the sinus node.

However, tachycardia significantly increases the risk of stroke, sudden cardiac arrest, and death. Beta blocker medicines also can slow the heart rate and decrease how forcefully the heart contracts. Tachycardia is generally caused by a disruption in the normal electrical impulses that control our heart's pumping action - the rate at which our heart pumps. However, the risk for serious bleeding doesn't occur until the count becomes very low—less than 10,000 or 20,000 platelets per microliter. Bradycardia typically does not cause symptoms until the rate drops below 50 BPM. In dogs, common causes include heart valve problems, heartworm disease, heart defects, tumors, or weakening of the heart muscle. The clinical relevance pertaining to AV blocks is greater than that of SA blocks.[11]. In some cases, the threshold is less than 50 BPM.
