Its quite uncertain why they cant solve the PVC issue. Since the sinus node that usually determines the heart rate is in the atrium, a block between the atria and ventricles causes a change in how fast the heart beats. It will detect pauses and their length. Our patient's tracing has the characteristic "sinus sign", wherein sinus rhythm is observed in a frontal or limb lead as demonstrated in leads III and V1 ( Figure 2 ). EKG artifacts can be generated by internal and external causes[3]. In addition to the sinus arrhythmias mentioned above, other types of sick sinus syndrome include: Atrial fibrillation (AFib) is the most common type of arrhythmia.
