ECG
Electrocardiogram – Essential Heart Assessment

At M R Hospitals, Thanjavur, our ECG service provides a quick, non-invasive assessment of the heart's electrical activity and rhythm.
An ECG is one of the most commonly performed cardiac investigations and can provide valuable information about heart rhythm, heart rate and certain abnormalities affecting the heart. 

What Is an ECG?

An Electrocardiogram (ECG) records the electrical signals generated by the heart through small electrodes placed on the chest and limbs.
It can provide information about:
• Heart rate
• Heart rhythm
• Electrical conduction
• Certain patterns suggestive of reduced blood supply to the heart
• Previous or ongoing cardiac injury
• Other electrical abnormalities
The test is quick, painless and does not involve radiation. 

When Is an ECG Recommended?
An ECG may be advised for patients with:

• Chest pain or discomfort
• Palpitations
• Breathlessness
• Dizziness
• Fainting or near-fainting
• Unexplained fatigue
• Suspected cardiac disease
• Known heart disease
• Abnormal pulse or heart rhythm

It may also form part of a routine medical evaluation when clinically indicated. 

ECG in Emergency Care

ECG is particularly important in emergency situations.
It can provide rapid information in patients presenting with:
• Acute chest pain
• Suspected heart attack
• Palpitations
• Severe breathlessness
• Fainting
• Unexplained collapse
Rapid ECG assessment allows the medical team to determine whether further urgent cardiac evaluation or treatment is required.

Preoperative ECG

An ECG may be performed as part of preoperative cardiac assessment, depending on the patient's age, medical history, symptoms and the type of surgery planned.
This is particularly relevant for patients undergoing major procedures, including:

• Gastrointestinal surgery
• HPB surgery
• Cancer surgery
• Thoracic surgery
• Bariatric surgery
• Other major operations

The findings can be considered by the anaesthesia and surgical teams during perioperative planning.

ECG & Other Cardiac Investigations

An ECG provides information about the heart's electrical activity, while other investigations assess different aspects of cardiac function.
When required, ECG findings can be complemented by:
• 2D Echocardiography – assessment of cardiac structure and function
• Laboratory investigations
• Other cardiac investigations as clinically indicated
This allows a more complete evaluation when symptoms or ECG findings require further assessment.

ECG in Hospitalised Patients

ECG services support patients across our:
• Emergency Department
• Outpatient services
• Inpatient wards
• Adult ICU
• Paediatric ICU
• Neonatal ICU
• Preoperative assessment services
Patients requiring further cardiac evaluation can be referred to the appropriate specialist team.
