Normal Heart Rate for Elderly Adults

A normal resting heart rate for most seniors is between 60 and 100 beats per minute. However, the resting heart rate for seniors can differ from their heart rate with regular exercise. To estimate a target exercise heart rate, you can subtract your age from 220 to estimate your maximum heart rate and calculate 50–85% of that number. According to the American Heart Association, the estimated target heart rate numbers for adults ages 45–70 are:

• 45 years: 88 to 149 beats per minute
• 50 years: 85 to 145 beats per minute
• 55 years: 83 to 140 beats per minute
• 60 years: 80 to 136 beats per minute
• 65 years: 78 to 132 beats per minute
• 70 years: 75 to 128 beats per minute

These are general estimates. Older adults with heart conditions or those taking medications that affect heart rate should consult their healthcare provider about appropriate exercise targets.

If a senior’s heart rate is too low or too high, it can be dangerous, and we will go over why in the next two sections.

Causes of Low Heart Rate in the Elderly

A low heart rate, or bradycardia, can cause severe health problems. This includes fainting, dizziness, fatigue, shortness of breath, chest pains, and memory problems. However, a low resting heart rate does not always indicate a medical problem, particularly in physically active individuals.

You should have a thorough medical evaluation to determine the cause of your low heart rate in elderly adults, but here is a brief look at some potential causes.

• Abnormal heart rhythms
• Atrioventricular (AV) node damage
• Certain heart conditions, including cardiomyopathy and congestive heart failure
• Chemical imbalances (such as calcium, electrolytes, and potassium)
• Heart attack
• Heart surgery complications
• Hypothyroidism and other thyroid disorders in elderly adults
• Inflammatory diseases
• Medication side effects
• Stroke
• Sick sinus syndrome

Treatment for bradycardia depends on its underlying cause. Managing blood pressure and cholesterol, avoiding smoking, limiting alcohol consumption, and managing stress can support overall heart health. However, some cases require medication adjustments or a pacemaker. Consult your doctor about the best steps to take.

Causes of a Fast Heart Rate in the Elderly

It’s normal to have a faster heart rate when performing physically demanding activities, but if your heart rate is higher than 100 beats per minute while at rest, you may have tachycardia. Certain forms of tachycardia, if left untreated, can lead to dangerous complications, including stroke, heart failure, or sudden cardiac arrest.

The exact cause of tachycardia cannot always be determined, but here are a few factors:

• Anemia in seniors
• Drinking too many caffeinated or alcoholic beverages
• Electrolyte imbalance
• Exercise
• Fever
• High or low blood pressure, including conditions that cause fluctuating blood pressure in elderly adults
• Hyperthyroidism
• Medication side effects
• Smoking
• Sudden stress, such as fright
• Stimulant drug use

Certain underlying heart conditions, including heart valve disease in the elderly, may also contribute to abnormal heart rhythms.

You can manage tachycardia through medications for underlying diseases, medical procedures, or, in certain cases, implanted cardiac devices. Treatment depends on the type and cause of the abnormal heart rate. As always, speak to your doctor if you have any concerns.

The Heart of the Matter

According to researchers from Harvard Medical School, one in four deaths in the United States is due to heart disease. Consider purchasing a wearable heart monitor to measure your heart rate and keep it in check.

Along with monitoring your heart rate, following practical tips to keep your heart healthy can support cardiovascular health as you age.

If you find that your heart rate is consistently abnormal, speak to your doctor about further evaluation and treatment. Seek emergency medical attention if an abnormal heart rate is accompanied by chest pain, fainting, or severe shortness of breath.
