Do Not Confuse Mobitz Type I and Mobitz Type II Atrioventricular (AV) Block
Key ECG Characteristics of Mobitz Type I and Type II AVB
Second-degree AVB is divided into two types, Mobitz type I and type II. It is important for the emergency provider to be able to distinguish between these two types of second-degree AVB, as treatment, disposition, and prognosis can be vastly different.

ECG Case 14
16 years old male with palpitation. What type of tachycardia do you think this patient has ?
Low QRS Voltage on the ECG
Small QRS complexes indicate that relatively little of the voltage generated by ventricular depolarization is reaching the ECG electrodes.
