Background:
Chronic Obstructive Pulmonary Disease (COPD) is associated with left atrial (LA) dyfunction, which may contribute to adverse cardiovascular outcomes. This study investigates the predictive value of lately identified morphology-voltage-P wave duration electrocardiography (MVP ECG) score for detecting early LA dysfunction in COPD patients.
Methods:
In this cross-sectional study, 101 COPD patients were enrolled. All patients underwent speckle tracking echocardiography and were classified into two groups based on their LA functions.
Results:
Our findings demonstrate significant variations in Peak Atrial Longitudinal Strain (PALS) values among COPD patients, with a mean PALS of 28.74 ± 1.81 % for the group with normal LA function and 18.44 ± 1.87 % for the group with abnormal LA function (p < 0.001). Despite similar LA diameters across groups, these variations indicate subclinical LA pathogenesis. ROC curve analysis indicated that an MVP ECG score greater than 2.5 predicted abnormal LA function with a sensitivity of 65 % and a specificity of 91 % (area under the curve [AUC]: 0.873; p < 0.001), suggesting its utility in identifying atrial damage and remodeling.
Conclusions:
The MVP ECG score shows promise as a tool for early detection of atrial remodeling in COPD patients.

01:28Electrocardiogram 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.

01:25Correlation 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...

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....
