THE DETAILS OF THE PHOTOGRAPHICALLY RECORDED VENOUS PULSE IN AURICULAR FIBRILLATION

Area of Science:

• Cardiology
• Physiology

Background:

• Auricular fibrillation is identifiable via arterial, jugular, and electrocardiogram tracings.
• Venous tracings in auricular fibrillation present distinct systolic and diastolic wave patterns.
• Prominent systolic waves are often attributed to tricuspid regurgitation, suggesting its commonality.

Purpose of the Study:

• To investigate the nature of systolic and diastolic waves in the venous pulse of auricular fibrillation patients.
• To clarify the association between venous pulse wave characteristics and tricuspid regurgitation.
• To differentiate between true regurgitation waves and artifactual wave forms in polygraph recordings.

Main Methods:

• Photographic recording of venous pulse waves in 25 clinical cases of auricular fibrillation.
• Analysis of six identified types of systolic waves.
• Comparison of venous pulse wave data with electrocardiogram findings.

Main Results:

• Tricuspid regurgitation, indicated by specific regurgitation waves, was found to be rare in auricular fibrillation.
• Intensified impact waves, signifying vigorous ventricular action, were common but often distorted by polygraph levers.
• These distortions can lead to misinterpretation, simulating regurgitation waves.
• Recurrent diastolic waves were frequently observed, but their relation to coarse fibrillation or flutter remains unproven.

Conclusions:

• Tricuspid regurgitation is not a common feature of auricular fibrillation.
• The apparent prevalence of regurgitation waves in prior studies is likely due to polygraph-induced distortions of intensified impact waves.
• The significance of recurrent diastolic waves in auricular fibrillation requires further investigation.
