Wenckebach heart block, also known as Mobitz Type I or second-degree AV block Type I, often does not require immediate intervention like cardioversion or a pacemaker unless it progresses or is associated with significant symptoms. It is characterized by a progressive lengthening of the PR interval on the ECG until a beat is dropped. This type of heart block is usually less severe than others and can be managed with observation for signs of decreasing cardiac output, making further observation the most likely initial approach.
