[!!50mm/s!!] Atrial arrhythmia? High grade AV block? What am I looking at
Woman with PMx of severe kidney failure, heart failure, ablation due to AF and been electrocardioverted x3 for afib/aflutter before. Now initially felt like she had atrial fibrillation for three hours before acute onset of central chest tightness.
I honestly have no idea what kind of rhythm this is. Have clear P-waves that seem dissociated from the QRS-complexes, but there are multiple identical PR-intervals. Is this some sort of conduction block?
