Sovari A, Zarghamravanbakhsh P, Shehata M. Temporary cardiac pacing. However, paramedics are still concerned about the patient's hypotension. Current is applied until electrical capture (characterized by a wide QRS complex since the SA node-AV node conducting pathway is bypassed, with tall, broad T-waves on the EKG) occurs. 4=!vC x kuQ The device and the manufacturer's multifunction electrodes (MFEs) shown here are used to deliver TCP. fluids, atropine, digibind, glucagon, high dose insulin). threshold to provide a safety margin. During transcutaneous pacing procedure, upon electrical and mechanical capture, it is recommended to increase the milliamps (mA) 10% higher than the threshold of initial electrical capture as a safety margin (usually 5-10 mA). Capture achieved at 110 mA confirmed with SpO2 plethysmograph, Pacing Artifact May Masquerade As Capture. In skilled hands, the semifloating transvenous catheter is successfully placed under electrocardiographic (ECG) guidance in 80% of patients.1 The technique can be performed in less than 20 minutes in 72% of patients and in less than 5 minutes in 30% ( Videos 15.1 - 15.3 ). External transcutaneous pacing has been used successfully for overdrive pacing of tachyarrhythmias; however, it is not considered beneficial in the treatment of asystole. This case will focus on the patient with a bradycardia and a heart rate less than 50/min. ACLS Medical Training does not provide medical advice, diagnosis, or treatment.
