Second-Degree Atrioventricular Block, Type II, is a cardiac conduction disorder characterized by a consistent block of electrical impulses from the atria to the ventricles, resulting in intermittent non-conducted QRS complexes.
Heart Rate: 60 to 100 beats per minute
Rhythm: Irregular
P wave: Normal P waves preceding conducted QRS complexes
PR Interval: Constant
QRS: 0.06-0.10 seconds
Second-Degree Atrioventricular Block, Type II, is diagnosed through clinical assessment and electrocardiogram (ECG) findings, which reveal consistent non-conducted QRS complexes.
"The management of 2° AVB Type II depends on the patient's clinical condition, symptoms, and the presence of any reversible causes. Treatment options include: Permanent Pacing: The hallmark of treatment for 2° AVB Type II is permanent pacemaker implantation. This is typically recommended to ensure a stable and reliable heart rate when there is a consistent block in the conduction system, as seen in this type of AV block. Medication Management: In some cases, medications may be used temporarily to support the heart rate while awaiting permanent pacemaker implantation. However, this is typically a short-term solution.
