The document summarizes the indications, contraindications, and normal ECG responses to a treadmill test (TMT). The TMT can be used to diagnose ischemic heart disease, vasospastic angina, and evaluate arrhythmias. Contraindications include fever, myocardial inflammation, severe aortic stenosis, uncontrolled hypertension, and unstable angina. During a TMT, the ECG normally shows an increased P wave, decreased R wave, depressed J point, upsloping ST segment, shortened QT interval, and decreased T wave.

3. INDICATIONS
⚫ Diagnosis Of IHD, Vasospastic angina
⚫ Post myocardial infarction
⚫ Evaluation of arrhythmias

4. Contraindications
• Fever/acute viral illness.
• Myocarditis/pericarditis.
• Severe aortic stenosis.
• Aortic dissection.
• Uncontrolled hypertension.
• Overt cardiac failure.
• Unstable angina or acute phase of MI.
• Signif cant resting arrhythmia (e.g. uncontrolled atrial fi brillation or
complete heart block).
• Known severe left main stem (LMS) or LMS equivalent disease.
• Physical disability.
• ECG abnormality rendering interpretation of ST segment diffi cult (e.g.
left bundle branch block (LBBB), left ventricular hyphetrophy (LVH)
with strain or digoxin ECG changes).

15. Normal response to ECG to stress
testing
ECG changes
⚫ P wave increase in height
⚫ R wave decrease in height
⚫ J point becomes depressed
⚫ St segment become sharply upsloping
⚫ Q-T interval shortens
⚫ T wave decreases in height
