The M mode echocardiogram is not the main priority, during routine echocardiographic evaluation now-a-days. However, there are still a few classical conditions where this remains instructive and educative. One such situation is the presence of an 'a' wave in the pulmonary valve M mode tracing in normals and it's absence in pulmonary hypertension. In valvular pulmonary stenosis we expect a deeper 'a' wave. We describe one more cause of a prominent 'a' wave in the pulmonary valve M mode. We describe this in a common tropical disease, endemic to Kerala.
如今,在常规超声心动图评估中,M型超声心动图并非首要重点。然而,仍有一些经典情况,M型超声心动图在这些情况中仍具指导和教育意义。其中一种情况是,正常情况下肺动脉瓣M型描记中有“a”波,而在肺动脉高压时则没有。在瓣膜性肺动脉狭窄中,我们预期会出现更深的“a”波。我们描述了肺动脉瓣M型中“a”波突出的另一个原因。我们将在喀拉拉邦特有的一种常见热带疾病中对此进行描述。
