Background:
We investigated the prognostic value of precordial total Q wave amplitude/precordial total R wave amplitude ratio (Q/R) in patients with first acute anterior MI treated with primary percutaneous coronary intervention (PPCI).
Methods:
We evaluated the in-hospital prognostic impact of Q/R on 354 patients with first acute anterior MI. Patients were stratified by tertiles of admission Q/R, clinical outcomes were compared between those groups.
Results:
In-hospital univariate analysis revealed notably higher rates of in-hospital death for patients in tertile 3, as compared to patients in tertile 1 (OR 9.7, 95% CI 2.8-33.5, p.
Conclusion:
Q/R in admission ECG in patients with first acute anterior MI provide an independent prognostic marker of in-hospital outcomes.

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....
Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...
Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
