[vc_row css=”.vc_custom_1592016883850{background-color: #fff9f9 !important;}”][vc_column][vc_column_text]The jugular venous pulse can provide a clue to the diagnosis of atrial fibrillation. The a wave of the jugular venous waveform occurs as a result of right atrial contraction. Because atrial fibrillation does not allow for coordinated atrial contraction, the a wave disappears. Similarly, since there is no atrial relaxation in the setting of atrial fibrillation, the x descent is smaller than normal.<\/span>

Patient 1:<\/h1>\n

This patient was admitted to the hospital with decompensated heart failure and atrial fibrillation. These videos demonstrate the typical features of the jugular venous waveform of atrial fibrillation: it is irregular, there is no a wave, and there is a diminutive x descent. The single dominant descent shown in these videos is the y descent. You could prove that at the bedside by observing the jugular venous pulse while simultaneously ausculting the heart or palpating the pulse. The x descent occurs at the same time as S1 and the peripheral pulse, while the y descent does not. <\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row css=”.vc_custom_1592016904930{background-color: #dcd9dd !important;}”][vc_column width=”1\/2″][vc_column_text]\n
