Resting heart rate

Bradycardia Bradycardia is a slow heart rate (60 beats per minute or slower) that does not meet the body s metabolic demands. Symptoms of bradycardia include dizziness, extreme fatigue, shortness of breath, or fainting spells. This can be compared to tachycardia, which is an extremely rapid heart rate, usually signified by a pulse of over 100 beats per minute. Adults usually have a resting heart rate of 70-80 beats per minute, although well-trained athletes can have resting rates in the 50 s or 60 s. Newborn babies have a normal heart rate of 120-160 beats per minute. A slowed heart rate can lead to a variety of other problems. First aid treatment may include administration of oxygen. 

Resting heart rate between 50 and 60 beats per minute. 

Maximum heart rate with exercise of 100 beats per minute or less or 20 beats per minute above the resting heart rate.

Many patients are asymptomatic, particularly those with normal resting heart rates less than 60 bpm as a result of physical fitness due to regular vigorous exercise. 

Tachycardia An abnormally rapid beating of the heart, defined as a resting heart rate over 100 beats per minute in an average adult. 

Using the ECG, the heart rate may be determined by calculating the time from the beginning of one P wave to the beginning of the next P wave, or from peak to peak of the QRS complexes. A normal resting heart rate in adults is approximately 70 beats/min. A heart rate of less than 60 beats/min is referred to as bradycardia and a heart rate of more than 100 beats/min is referred to as tachycardia. 

Joel s resting heart rate is about 71 beats per minute. If Joel is at rest for 35.2 minutes, about how many times will his heart beat during that period of time ... 

Therapy should be initiated with propranolol, 10 mg three times daily, or nadolol, 20 mg once daily, and titrated to a reduction in resting heart rate of 20% to 25%, an absolute heart rate of 55 to 60 beats/min, or the development of adverse effects. 

The resting heart rate of 60-80 bpm results from dominant vagal tone. The intrinsic rate generated by the sinoatrial (SA) node is 110 bpm. Control of heart rate is, therefore, through the balance of parasympathetic and sympathetic activity via the vagus and cardioaccelerator (T1-T5) fibres, respectively. 

In neonates and children the sympathetic system is relatively underdeveloped while the parasympathetic supply is relatively well formed. Despite a high resting heart rate in this population, many insults may, therefore, result in profound bradycardia. The most serious of these insults is hypoxia.

The hemodynamic effects of sotalol are related to its 3-adrenoceptor antagonist activity. Accordingly, decreases in resting heart rate and in exercise-induced tachycardia are seen in patients receiving sotalol. A modest reduction in systolic pressure and in cardiac output may occur. The reduction in cardiac output is a consequence of lowering the heart rate, since stroke volume is unaffected by sotalol treatment. In patients with normal ventricular function, cardiac output is maintained despite the decrease in heart rate because of the simultaneous increase in the stroke volume. 

Postmyocardial infarction-. Left ventricular function, lower resting heart rate... 

Bradycardia If it taken, resting heart rate reduces to 60/min or less. 

With heart disease being the number one cause of death among older Americans, you should pay particular attention to known causes of heart disease. A healthy heart can continue to function as well at 70 as it did at 30. If your heart is not affected by disease, your resting heart rate remains the same throughout your life. The question, then, is what can you do to keep it healthy Here are five suggestions.

Q2 In addition to poor memory, factors which suggest a diagnosis of hypothyroidism include cold intolerance, cold extremities, slowed reflexes, low resting heart rate, slow thought processes, depression and sleepiness/lack of energy, appetite suppression associated with weight gain and raised blood lipids, which may lead to increased atherosclerosis.
