Understanding the Basics of ECG: What You Need to Know

India is a rising country, not only based on development but also on the basis of heart diseases & number of deaths due to heart attacks as well. In recent data, it has been shown that the number of deaths due to heart attacks remained at over 25,000 per year over the past four years while in the last three years, the number is over 28,000. The medical news statistics have stated that 50% population of India experiences one heart attack before the age of 55. A huge number of younger people are developing heart diseases & many times children are getting born with some heart issues as well. Kerala is leading in terms of the severity of heart disease. 19.90 per cent of people in Kerala have a dangerously increased risk of heart disease. However, the risk of heart attack or the number of deaths can be reduced by proper medication & care. Well, for that, people need to go through various heart check-ups such as ECG (Electrocardiogram). In this blog, we will inform you of the basics of ECG & its importance for your long & healthy life.


1. What is an ECG (Electrocardiogram)?

Electrocardiogram which is also called ECG is a heart test which records the electrical signals in the heart. Normal ECG values for waves and intervals are as follows: RR interval: 0.6-1.2 seconds. P wave: 80 milliseconds. PR interval: 120-200 milliseconds. Any increase or decrease in these parameters is a sign of your heart issues.

Well, in this case, it is important to mention that even if you do not have any symptoms of having a heart issue, do not forget to have a yearly check-up. This regular check-up helps in the detection of many issues in the early stage & also helps in easy curation.

2. Why does an ECG or Electrocardiogram get done?

An electrocardiogram is a painless, noninvasive way which helps to diagnose many heart issues such as
● Any kind of irregular heart rhythm (arrhythmia).
● If blocked or narrowed arteries are present in the heart (coronary artery disease) are causing chest pain or a heart attack
● Whether you have had a previous heart attack
● How well certain heart disease treatments, such as a pacemaker, are working or not.


3. Why does a doctor suggest an ECG?

A doctor usually suggests an ECG if you experience the symptoms mentioned below-
● Chest pain
● Dizziness, lightheadedness or confusion
● Heart palpitations
● Rapid pulse
● Shortness of breath
● Weakness, fatigue or a decline in the ability to exercise
Usually, these are the symptoms of underlying heart issues. To be assured about the disease the doctor suggests ECG to the patients.

4. What are the types of ECG?

There are three types of ECG and the types are-

a. Resting ECG: Resting ECG (electrocardiogram) is the most common and easiest type of ECG. It is done when the patient is lying or sitting comfortably. That is why it is called “Resting ECG”. Well, it is usually done as a part of routine health check-ups, even before any symptoms. To get this test done 12 electrodes are placed on the patient’s chest, arms, and legs at the same time. For this reason, this test is also called a resting 12-lead EKG. In this test, the patient needs to sit for just 5 to 10 minutes only and this test reflects your heart at rest. It is important to mention that it is the most common or most used type of ECG test in India and also the patient does not need to do any preparation for this test. They can consume normal food & medicines (if prescribed) before the test.

b. Exercise ECG: The second type is the exercise ECG, also known as a treadmill test or stress test. This test is done when the patient is walking on a treadmill or pedalling a stationary bicycle. The intensity of the exercise also increases with time to record different breathing rates and also the blood pressure gets monitored.
Usually, this test is done to detect any coronary artery diseases or to determine the safe exercise level for a patient after they’ve had a heart attack or heart surgery. The patient needs to do fast & must refrain from medicines for an accurate result.

c. Holter Monitor: The third ECG type is the Holter Monitor. Holter monitor or ambulatory ECG is a type of electrocardiogram that’s used to continuously monitor the ECG tracking for a duration of 24 hours or longer. In this process, small plastic patches or electrodes are applied to specific areas. The electrode stays attached to a small portable machine which the doctor will place at the waist of the patient to track the heartbeat throughout the time. These electrodes help to monitor & measure the heartbeat. Most of the time, doctors take a printout of this for future reference.
