Overview of Electrocardiogram (ECG)

An Electrocardiogram (ECG) is a simple, quick, and painless test that measures the electrical activity of the heart. It helps detect abnormalities in heart rhythm, rate, and structure. As one of the most commonly used cardiac diagnostic tools, an ECG provides essential information for identifying conditions such as arrhythmias, heart attacks, and other heart-related issues. Under the care of Dr. Karthik Raghuram, patients receive highly accurate ECG interpretation and guidance based on results.

Why an ECG Is Important

The heart generates electrical signals that control each heartbeat. When these signals become abnormal, it can indicate underlying problems. An ECG helps:

• Diagnose irregular heart rhythms

• Detect signs of heart attack or previous cardiac damage

• Identify abnormalities in heart size

• Evaluate chest pain or palpitations

• Monitor the effects of medications

• Assess heart health before surgery

Early detection through ECG can prevent serious complications.

When Should You Get an ECG?

You may require an ECG if you experience:

• Chest pain or discomfort

• Palpitations or fluttering sensation

• Shortness of breath

• Dizziness or fainting

• Fatigue and reduced stamina

• High blood pressure

• Unexplained anxiety episodes

ECG is also recommended for individuals with:

• Diabetes

• High cholesterol

• Family history of heart disease

• History of smoking

• Ongoing cardiac treatment

Regular ECG monitoring is essential for patients with known heart conditions.

How an ECG Test Is Performed

An ECG is a quick and non-invasive test performed as follows:

• Electrodes are placed on the chest, arms, and legs

• The machine records the heart’s electrical activity

• The process takes 2–5 minutes

• There is no pain, discomfort, or recovery time required

Dr. Karthik ensures accurate readings by correlating ECG findings with symptoms and clinical history.

Types of ECG Tests

Depending on the patient’s condition, different ECG types may be used:

1. Resting ECG

Standard test performed while the patient lies still.

2. Stress ECG (Treadmill Test – TMT)

Measures heart activity during exercise to detect blockages.

3. Holter Monitoring (24–48 hours)

Continuous ECG recording to identify intermittent arrhythmias.

4. Event Recorder

Used for long-term evaluation of occasional abnormal heartbeats.

Each test is chosen based on the patient’s symptoms and diagnostic needs.

Conditions Detected by ECG

An Electrocardiogram can help diagnose:

• Atrial fibrillation and other arrhythmias

• Heart attack (current or previous)

• Coronary artery blockage indicators

• Electrolyte imbalances

• Pericarditis (inflammation around the heart)

• Enlargement of heart chambers

• Conduction abnormalities

An ECG is often the first step to identify heart issues quickly and accurately.

Benefits of ECG Testing with Dr. Karthik Raghuram

Patients benefit from:

• Accurate interpretation by an experienced cardiologist

• Quick diagnosis and treatment decision

• Early detection of life-threatening conditions

• Access to further cardiac evaluation if needed

• Personalised care based on ECG results

When to Seek Immediate ECG Evaluation

Seek urgent ECG testing if you experience:

• Sudden chest pain

• Severe breathlessness

• Rapid or irregular heartbeat

• Dizziness or fainting

• Pain spreading to arm, neck, or jaw

These may indicate a cardiac emergency.
