A cardiologist is a medical doctor who studies and treats diseases and conditions of the cardiovascular system – the heart and blood vessels – including heart rhythm disorders, coronary artery disease, heart attacks, heart defects and infections and related disorders.

Although cardiologists can't perform surgery, there are some specialized procedures that they can perform. For example, an interventional cardiologist may use a stent to open clogged arteries. Apart from this, they can implant some advanced devices in the heart of the patient suffering from some heart related disorders.

A cardiologist is a doctor who specializes in the care of your heart and blood vessels. They can treat many heart problems or help you prevent them. They may also specialize in specific areas, such as abnormal heart rhythms, heart failure, or heart problems you've had since birth.

Electrocardiogram (ECG) is a test that records the electrical activity of the heart. The ECG shows what is happening in different areas of the heart and helps to identify any problems with your heart's rhythm or rhythm. ECG is painless and takes about 5-10 minutes to do.

The normal resting heart rate for adults ranges from 60 to 100 beats per minute. In general, a lower resting heart rate means more efficient heart function and better cardiovascular fitness.

An echocardiogram can help diagnose and monitor certain heart conditions. It examines the structure of the heart and surrounding blood vessels, analyzes how blood flows through them, and assesses the pumping chambers of the heart.

Heart disease refers to any problem affecting the heart, such as coronary artery disease, arrhythmias, and heart failure. Lifestyle choices can prevent many of these conditions, and medicine can help manage them if they do occur.

Cardiomyopathy is a disease in which the heart muscle becomes weak, stretched, or has some other structural problem. This often contributes to the heart's inability to pump or function properly. Many people with cardiomyopathy develop heart failure.

Go to your doctor. You may have trouble breathing, an irregular heartbeat, swollen legs, varicose veins in your neck, and hoarseness from fluid in your lungs. Your doctor will check for these and other signs of heart failure. A test called an echocardiogram is often the best test to diagnose your heart failure.

Heart failure can begin suddenly after your heart muscle is damaged by a medical condition or injury. But in most cases, heart failure develops gradually due to long-term medical conditions. Conditions that can cause heart failure include: Arrhythmia (a problem with the rate or rhythm of your heartbeat)
