Key result
Transthoracic echocardiography in a patient with 2:1 atrioventricular block revealed retrograde flow into the left atrium after the blocked P-wave, indicating holodiastolic mitral regurgitation.
Case Report (n=1)
This case report demonstrates the utility of echocardiography in identifying holodiastolic mitral regurgitation in a patient with 2:1 atrioventricular block.
Echocardiography may detect holodiastolic MR in 2:1 AV block; single case leaves open prevalence and clinical relevance.
Mini‐Abstract We present a 74‐year‐old man with a history of hypertension presented to the emergency room with shortness of breath and dizziness. A resting electrocardiogram showed 2:1 atrioventricular block with a wide QRS duration and a rhythm of 35 beats/min. Transthoracic echocardiography was performed and color flow Doppler, color M‐mode, and continuous‐wave Doppler recordings of the transmitral flow revealed retrograde flow into the left atrium after the blocked P‐wave, which indicate holodiastolic mitral regurgitation.

Kocabay et al. (2012) conducted a case report in 2:1 atrioventricular block and diastolic mitral regurgitation (n=1). 2:1 atrioventricular block was evaluated on Holodiastolic mitral regurgitation. Transthoracic echocardiography in a patient with 2:1 atrioventricular block revealed retrograde flow into the left atrium after the blocked P-wave, indicating holodiastolic mitral regurgitation.
