Question
On an ECG, a long P-R interval might indicateMultiple Choicean AV node block.tachycardia.sinus arrhythmia.atrial fibrillation.an SA node block.
Solution
On an ECG, a long P-R interval might indicate an AV node block.
Here's why:
-
The P-R interval on an ECG represents the time it takes for an electrical impulse to travel from the atria (the heart's upper chambers), through the atrioventricular (AV) node, and then to the ventricles (the heart's lower chambers).
-
If this interval is longer
