When an S wave is present in all of the limb leads the frontal plane axis is indeterminate. This can be a normal variant but when the QRS complex is net negative in limb lead I, consistent with a rightward axis, usually right ventricular hypertrophy or dilation is the underlying cause. However, this is a rare ECG finding in asymptomatic adults.
A 70-year-old patient with a history of hypertension has a blood pressure of 180/100 mm Hg and a heart rate of 90 beats per minute. The nurse hears an extra heart sound at the apex immediately before the S1. The sound is heard only with the bell of the stethoscope while the patient is in the left lateral position.
"Distant heart sounds" is doctorspeak for "I couldn't hear the heart sounds very well and I think that was because the heart is far away from my stethoscope." Typically the reason for this is obvious -- either the patient is overweight or has an expanded chest because of lung disease such that either fat or air has created distance between the ...
The algorithm uses discrete wavelet decomposition and reconstruction to produce PCG intensity envelopes and separates that into four parts: the first heart sound, the systolic period, the second heart sound and the diastolic period.

- Apr 27, 2018 · The mechanical activity of heart due to its physical movement produces four distinct sounds or beats which are named as first normal heart sound (S1), second normal heart sound (S2), third abnormal heart sound (S3), and fourth abnormal heart sound (S4). S1 and S2 are normal sounds while S3, S4, murmurs, and certain other sounds usually refer to some disease or anomaly.
- The most fundamental heart sounds are the first and second sounds, usually abbreviated as S1 and S2.
