In early diastole, the blood through ventricle from atrium in failing myocardium. the ventricular wall tension Is poor, produce vibration. Reflex that the ventricular functiony Auscultation character of S3 gallop lower in pitch After S2 Best hear at apex Loudest at the end of expiration
– In early diastole, the blood through into ventricle from atrium in failing myocardium, the ventricular wall tension is poor, produce vibration. Reflex that the ventricular function • Auscultation character of S3 gallop: – lower in pitch – After S2 – Best hear at apex – Loudest at the end of expiration
S3 gallop: differ from normal S3 Occur in severe organic heart disease HR>100 bpm The interval time between s1 and s2 are almost equal, mimicking quality, normal S3 is nearer from S2 Normal s3 will disappear in standing or Sitting position
• S3 gallop: differ from normal S3 – Occur in severe organic heart disease – HR>100 bpm – The interval time between S1 and S2 are almost equal, mimicking quality, normal S3 is nearer from S2 – Normal S3 will disappear in standing or sitting position
Late diastolic gallop S4 gallop, atrium gallop At late diastole. related to atrial contraction In Lvedp个 compliance Artial contraction↑ occur precede s, far from s? low-pitch: best heard at apex Tensity: end of expiration(from LA end of inspiration T(from RA)
• Late diastolic gallop – S4 gallop, atrium gallop • At late diastole, related to atrial contraction. In LVEDP compliance Artial contraction occur precede S1 , far from S2 low-pitch; best heard at apex • Tensity: end of expiration(from LA) end of inspiration (from RA)
Occur in pressure overload, >LVH, in myocardial damaged, LV compliance V such as bp↑ISS.CHD
• Occur in pressure overload,→LVH, in myocardial damaged , LV compliance , such as BP, IHSS, CHD
