Heart Rate

What is Heart Rate?
When the heart receives and pumps blood, The heart generates the electrical impulse that in turn makes the heart beat happen. Heart rate (HR) is the number of heart beats per unit time, usually per minute(bpm). Heart rate can be measured by monitoring one's pulse. Pluse is the result of heart beat. Heart rate usually measured to obtain a quick evaluation of a person's health.If heart rate of adult is very fast (over 100 beats per minute), this is called tachycardia. An unusually slow heart rate is called bradycardia.

Normal heart rate
For an adult(age 18 and over), a normal  heart rate ranges from 60 to 100 beats per minute (bpm). Usually women's heart rate is between about 70-80 beats per minute. Children's heart rate varies with age(See the table). Healthy young adults, men and women being physically active and athletes who often have heart rates of less than 60 beats a minute can be normal. Heart rate varies significantly between individuals based on fitness, age and genetics.

Children's heart rate
Age  group Heart Rate (bpm)
Newborn 140
6 months 130
1 yr 115
2 yr 110
6 yr 103
8 yr 100
10 yr 95

Tachycardia

Tachycardia refers to a rapid heart rate, A rate faster than 100 beats a minute in an adult is called tachycardia, this rate is usually based upon age(See the table). When the heart beats rapidly, the heart pumps less efficiently and provides less blood flow to the rest of the body, the

increased heart rate also leads to increased work and oxygen demand for the heart.This may lead to heart attack.

Cause of tachycardia

  • Normal heart rate increase as response to various situations, such as Exercise or exertion, emotion, anxiety, Nervousness etc.
  • Certain stimulating substances, such as excess adrenaline,nicotine,Caffeine,Illicit drugs and Certain medications.
  • Some diseases and different heart problems, such as high blood pressure (hypertension), fever, abnormalities of the heart valves, Pericarditis, etc.
  • Cardiac Arrhythmias include: Sinus tachycardia, ventricular tachycardia and Supraventricular tachycardia.
Diagnosis of tachycardia

1.Heart Monitoring Tests
Two heart monitoring tests: active and passive.
Active Tests
  • Electrophysiology (EP) testing and mapping
  • Stress test
Passive Tests
  • Electrocardiogram (ECG)
  • Holter monitor
  • Echocardiogram
2.Blood Test
Blood test can help to identify whether medications or substances, a thyroid problem are causing the tachycardia.

Bradycardia(slow heart beats)

Bradycardia is defined as a slow or irregular heart rhythm. If the heart rate of adult is slow, or less than 60 beats a minute, it is considered bradycardia.   For infants, bradycardia is defined as when the baby's heart rate slows down to less than 100 beats per minute.Symptoms of bradycardia include fainting, dizziness, extreme tiredness, and shortness of breath.
Cause of bradycardia
  • The natural aging process
  • A hereditary heart defect
  • Heart block
  • Sick sinus syndrome (or sinus node dysfunction)
  • medications or substances cause bradycardia
  • Certain illnesses cause bradycardia
  • Scar tissue from a heart attack
Diagnosis of bradycardia

1.Heart Monitoring Tests
Two heart monitoring tests: active and passive.
Active Tests
  • Electrophysiology (EP) testing and mapping
  • Stress test
Passive Tests
  • Electrocardiogram (ECG)
  • Holter monitor
  • Echocardiogram
2.Blood Test
Blood test can help to identify whether medications or substances, a thyroid problem are causing the bradycardia.
