  2. Mobitz type II second-degree atrioventricular block (AVB) is an electrocardiographic pattern that describes what appears to be an all-or-none conduction without visible changes in the AV conduction time or PR intervals before and after a single non-conducted P wave.

  3. 6 kwi 2023 · Second-degree AV block – Intermittent atrial conduction to the ventricle, often in a regular pattern (eg, 2:1, 3:2), or higher degrees of block, which are further classified into Mobitz type I (Wenckebach) and Mobitz type II second-degree AV block.

  4. Consider temporary pacing as soon as Mobitz II is identified; Patients require admission and cardiac monitoring; Unstable patient: cardiogenic shock; ALS; Apply pacing pads; IV access; Management of bradycardia; Atropine 500mcg IV STAT every 3-5 minutes (max 3mg) May not respond +/- Dobutamine infusion 3-20mcg/kg/min; Or Adrenaline infusion ...

  5. Blok przedsionkowo-komorowy II stopnia: blok typu Mobitz I (dawniej: Wenckebacha), charakteryzujący się stopniowym, z każdą ewolucją serca, wydłużaniem odstępu PQ, aż do wypadnięcia zespołu QRS (tzw. periodyka Wenckebacha).

  6. CRITICAL ACTIONS. Obtain IV access with two large bore peripheral IVs. Early fingerstick glucose. Place patient on cardiac monitor with continuous oxygen saturation monitoring. Ask for a full set of vital signs including HR, BP, oxygen saturation, and temperature.

  7. Differentiate Mobitz type 1 block from Mobitz type 2 block. Both Mobitz type 1 block and type 2 block result in blocked atrial impulses (ECG shows P-waves not followed by QRS complexes). The hallmark of Mobitz type 1 block is the gradual prolongation of PR intervals before a block occurs.
