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 18
Elderly man with Ischemic Heart Disease on therapy with Digoxin and Lasix. What abnormalities do you see ?
ECG Case 15
75 years old man presented with palpitations. What are you thoughts on this Tachyarrhythmia?
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.
