Cardiac rhythm refers to the pattern of electrical activity in the heart that regulates the heartbeat. It determines the timing and frequency of heartbeats and is primarily controlled by the heart’s natural pacemaker, the sinoatrial (SA) node.

A heart arrhythmia is an irregular heartbeat. It occurs when the electrical signals that tell the heart to beat don’t work properly. The heart may beat too fast or too slow. Or the pattern of the heartbeat may be inconsistent.

A heart arrhythmia may feel like a fluttering, pounding or racing heartbeat. Some heart arrhythmias are harmless. Others…[Read more]

What is Hypertension?
Hypertension, also known as high or raised blood pressure, is a condition in which the blood vessels have persistently raised pressure. Blood is carried from the heart to all parts of the body in the vessels. Each time the heart beats, it pumps blood into the vessels. Blood pressure is created by the force of blood pushing…[Read more]

Hypertension, also known as high blood pressure, is a condition where the force of blood pushing against your artery walls is consistently too high. It’s often called the “silent killer” because it usually doesn’t have any noticeable symptoms.

The muscular system is a network of tissues that allow for movement, posture maintenance, and heat generation. It consists of three types of muscle: skeletal, cardiac, and smooth. Skeletal muscles are attached to bones and allow for voluntary movement, while cardiac muscle is found in the heart and is responsible for involuntary contractions.…[Read more]

The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle…[Read more]
