Heart Problems – Causes and Treatment of Heart Blockage

Last Updated on May 31st, 2022

What is Heart Blockage :- In simple words we say “Abnormal heart rhythm when the heart beats too slowly and thus resulting in partially or completely blocking of signals between the atria and ventricle that is the upper and lower chamber of the heart.” Not simple ? Then let us try to explain you in other words.

Heart blockage disrupts the normal rhythm of the heart. An unhealthy heart with blockage causes difficulty in pumping blood properly through the circulatory system and thus the organs and even brain, do not get enough oxygen thus leading to improper functioning of the body.

The building of a waxy substance called plaque, in the coronary artery can lead to coronary heart disease leading to clogging of arteries. Coronary heart problems can produce symptoms such as chest pain, angina, or even Heart attack if not investigated and treated on time.

Due to improper lifestyle, it is likely observed by the age of 40 about half of us develop cholesterol deposits in our arteries and at about 45 years of age a lot of plaque buildup. However, in women, this could be observed after the age of 55. A study conducted shows heart ailments caused more than 2.5 million death in India in 2015. In India, a lot of many factors contribute to the same that includes poverty, lack of proper medical care, improper lifestyle, smoking, ignorance, and most importantly lack of awareness for the same.


QUICK FACT – According to a study conducted by The Lancet,  Deaths from heart-related diseases among rural Indians have surpassed urban Indians. The data from National Rural Health Mission shows 8 percent of primary health care centers in rural areas were functioning without a doctor, while 61 % had only one doctor as of March 2017.

Types of Heart Blockages

Heart block can be characterized into 3 types –

First degree –  This type is called a Minor blockage in heart, in which there are minor heartbeat disruptions that include skipped beats. It is considered as least serious and usually does not require any treatment like to unclog arteries.

Second degree – In this type of heart blockage, electrical signals never reach the heart and the patient might need a pacemaker.

Third-degree – In patient with heart disease, electrical signals do not travel between the upper and lower chamber. If the pacemaker, is not given there is a serious risk of heart problems to the patient.

Causes of Heart Blockage

Electrical impulses traveling inside the heart muscle instruct a healthy heart, to beat and contract. The impulse travel from the upper chamber to the lower chambers.

Damage to one of the branch bundles can cause ventricular contractions that result in an abnormal heartbeat.  A block on the left side is much more serious than a block on the right side since the block on the left side indicates a risk of coronary artery disease or some other major heart problem.
