3rd degree block: They've broken up, and are now doing things completely separately, no longer aligned. (P and QRS now have their own completely differing rhythms) Edit: First gold!

2018年2月2日 · For all my homies studying for step 2, let me make it as simple as I can: to distinguish Mobitz II from 3rd degree, look at PR interval.

Atrial fibrillation (AF or afib) is the most common irregular heartbeat and is characterized by heart palpitations, dizziness, and shortness of breath. This progressive and debilitating disease can lead to stroke, heart failure, and Alzheimer's disease, and can double your risk of death.

2021年1月26日 · I prefer the heart block poem: If R is far from P, then you have a First Degree Longer, Longer, Longer, Drop! Then you have a Wenckebach If some Ps don't get through, then you have a Mobitz II. If the Ps and Qs don't agree, then you have a 3rd degree.

2024年3月26日 · It just feels very unsafe for the patients. Every heart rhythm seems like it’s up for debate and it’s hard to agree with my coworkers on them. I’ve brought this up to the directors so now we rotate nurses in our monitor room for 1-day of training. (RHYTHM IN IMAGE) Here’s a heart rhythm that really tripped me up: (Only shows lead II)

2020年10月11日 · Just a little more info: this patient had open heart surgery and had AV epicardial wires in. This was all recorded while the patient was awake in bed in the CVICU. When the pacer was paused, this was the resulting rhythm, and the patient was asymptomatic. The pacer was paused a few times, and each time, that extra lone P was at the start of the ...

2022年8月2日 · Absolutely NOT a 3rd degree/complete heart block. There is an association of every P-wave with every QRS (ignoring the PVCs). In Complete Heart Block, the P-P interval will be the same, and the R-R interval will be, as well. However, there's no association between the two. You're girlfriend's instructor is an idiot

2014年6月20日 · This explains how to identify certain kinds of arrhythmia on an ECG/EKG. Heart block is essentially where two parts of the heart that should work together don't. There are varying degrees 1,2,3 plus a few little extras. Each have different identify features on …

No conducted p waves defines 3rd degree block and causes AV dissociation. 3rd degree block often has junctional escape with a narrow QRS and a slowish rate (textbook 40-60) so you end up with atrial contraction at a different rate from ventricular contraction and thus AV dissociation.

2023年3月28日 · Agree with everyone else saying atrial flutter. Upright in V1 but that would make me think it was counterclockwise CTI dependent flutter however there are not sawtooth appearing flutter waves in the inferior leads. The atrial rate is ~250-275 which makes it more likely a strange flutter than an A-Tach with block.
