السلام عليكم
كيفكم ؟شوو اخباركم؟محتاجة مساعدة منكم اتمنى في حد يعرف كيفية حل هذا السوال
1. A patient has ventricular bigeminy: every second pulse from the SA node is replaced
by a premature ventricular ectopic beat (PVC) with a full compensatory pause.The SA-node rate is regular at 80 beats a
minute, and each ectopic beat precedes the blocked SA-node pulse by 100 ma.
Draw a schematic three-channel representation of the ECG, the atrial electrogram (or
SA-node firing pattern), and the firing pattern of the ectopic focus for 10 beats, marking
the time scale in detail. Identify the correspondences and relationships between the
activities in the three channels.
2. Draw schematic representations of the ECG, PCG, and carotid pulse signals. Label all
waves in the three signals. Identify their common relationships to events in the cardiac
cycle.
