Understanding ECG (Electrocardiogram)

An electrocardiogram (ECG or EKG) is a painless, non-invasive test that records the electrical activity of your heart. For respiratory patients, ECG is crucial as many lung conditions can affect heart function, and cardiac issues can present with respiratory symptoms. Our comprehensive ECG evaluation helps identify cardiovascular complications and guides appropriate treatment.

Why ECG is Important for Respiratory Patients:

  • Detects heart complications from lung diseases
  • Identifies pulmonary hypertension effects on heart
  • Monitors cardiac effects of respiratory medications
  • Screens for cardiac causes of shortness of breath
  • Evaluates exercise tolerance and cardiac fitness
  • Assesses risk before procedures or surgeries

Types of ECG Testing Available

Resting ECG (12-Lead)

Procedure: Standard 12-lead ECG recorded while patient is at rest lying down.

Duration: 5-10 minutes including preparation and recording

Purpose: Baseline cardiac rhythm assessment, conduction abnormalities, structural heart disease

Best For: Routine screening, chest pain evaluation, pre-procedural assessment

Exercise Stress ECG

Procedure: Continuous ECG monitoring during treadmill or bicycle exercise testing.

Duration: 30-45 minutes including pre-test preparation and recovery

Purpose: Detect exercise-induced cardiac abnormalities, assess exercise tolerance

Best For: Coronary artery disease detection, exercise capacity evaluation

Holter Monitor (24-48 Hour)

Procedure: Portable ECG device worn for 24-48 hours for continuous monitoring.

Duration: 24-48 hours of continuous recording

Purpose: Detect intermittent arrhythmias, assess heart rate variability

Best For: Palpitations, syncope, suspected arrhythmias

Event Monitor

Procedure: Patient-activated recording device worn for weeks to months.

Duration: 2-4 weeks of intermittent monitoring

Purpose: Capture infrequent cardiac events when symptoms occur

Best For: Rare palpitations, infrequent syncope, medication monitoring

Cardiac Conditions We Detect

Arrhythmias (Rhythm Disorders)
  • Atrial fibrillation and flutter
  • Ventricular tachycardia and fibrillation
  • Bradycardia and heart blocks
  • Premature ventricular contractions (PVCs)
  • Supraventricular tachycardia (SVT)
Structural Heart Disease
  • Left ventricular hypertrophy
  • Right heart strain (cor pulmonale)
  • Atrial enlargement
  • Congenital heart defects
  • Cardiomyopathy changes
Ischemic Heart Disease
  • Acute myocardial infarction
  • Old myocardial infarction
  • Ischemic changes during exercise
  • Unstable angina patterns
  • Silent ischemia
Pulmonary-Cardiac Interactions
  • Pulmonary hypertension effects
  • Cor pulmonale (right heart failure)
  • Pulmonary embolism patterns
  • Sleep apnea cardiac effects
  • COPD-related cardiac changes

ECG Procedure Steps

1
Pre-Test Preparation

Patient History: Review of symptoms, medications, and previous cardiac history.

Preparation: Remove jewelry, change into hospital gown, inform about pacemaker or implants.

2
Electrode Placement

Skin Preparation: Clean and prepare skin for optimal electrode contact.

12-Lead Setup: Precise placement of 10 electrodes on chest, arms, and legs for comprehensive view.

3
Recording Process

Patient Positioning: Comfortable lying position with relaxed muscles.

Signal Acquisition: 10-second recording of electrical activity from multiple angles.

4
Quality Check

Trace Review: Immediate assessment of recording quality and artifact presence.

Repeat Recording: Additional recordings if needed for optimal quality.

5
Analysis & Interpretation

Computer Analysis: Automated measurements of intervals, axis, and rhythm.

Expert Review: Physician interpretation with clinical correlation and recommendations.

6
Results & Follow-up

Report Generation: Detailed written report with findings and clinical significance.

Patient Discussion: Explanation of results and any necessary follow-up or treatment.

ECG Parameters & Normal Values

Heart Rate & Rhythm
  • Normal Heart Rate: 60-100 beats per minute
  • Regular Rhythm: Sinus rhythm with consistent intervals
  • P Wave: Present before each QRS, upright in lead II
  • QRS Complex: Narrow (<120 ms), consistent morphology
Intervals & Measurements
  • PR Interval: 120-200 ms (normal conduction)
  • QRS Duration: <120 ms (normal ventricular conduction)
  • QT Interval: <440 ms (corrected for heart rate)
  • Axis: -30° to +90° (normal electrical axis)
When to Seek Immediate Care
  • Chest pain or pressure
  • Severe shortness of breath
  • Rapid or irregular heartbeat
  • Dizziness or fainting
  • Severe fatigue or weakness
