This type of block suggests a block lower in the conduction system, often within the bundle branches of the His-Purkinje system. This results in a mismatch where not every atrial contraction is followed by a corresponding ventricular contraction.
Managing Heart Block With Medication Therapy
Mobitz Type I (Wenckebach) Mobitz Type I is characterized by a progressive lengthening of the PR interval on the ECG until an impulse is finally blocked, resulting in a dropped beat. This condition requires careful evaluation because it sits between the benign irregularities of first-degree block and the life-threatening complete heart block.
This progression can lead to severe bradycardia, syncope, or sudden cardiac arrest, making it a condition that frequently requires immediate intervention with a pacemaker. Common complaints include dizziness, lightheadedness, fatigue, shortness of breath, chest pain or discomfort, and palpitations where the patient feels a sudden "pause" or "skipped" beat.

This type is often considered less serious because the block usually occurs at the level of the AV node. This pattern creates a repeating cycle where the R-R interval gradually shortens until a P wave appears without a corresponding QRS complex.
