WebIn such cases a compensatory pause creates conditions for PVC occurrence, and hence bigeminy persisting so long as the compensatory pause remains sufficiently long (see Figures 17-1 and 17-6). According to the rule, bigeminy disappears when the heart rate increases, which is usually the case ( Figure 17-9 ). WebCardiac Auscultation. Auscultation of the heart requires excellent hearing and the ability to distinguish subtle differences in pitch and timing. Hearing-impaired health care practitioners can use amplified stethoscopes. High-pitched sounds are best heard with the diaphragm of the stethoscope. Low-pitched sounds are best heard with the bell.
