EMS reports intermittent sinus tachycardia and bradycardia secondary to some type of heart block during transport. It is hard to make out P waves but you can see them best in V2, and notches in the T waves in other leads - this is a sinus tachycardia with a very long PR interval indicating first degree block.

Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered. Nevertheless, the widths of both the QRS complex and the RS duration are similar in both the old ECG and the tachycardia.

There are three mechanisms of arrhythmia: automatic, re-entry, and triggered. The most common triggered arrhythmia is Torsades de Pointes. Automatic activity refers to enhanced pacemaking function (typically from a non sinus node source), for example atrial tachycardia. This has been discussed many times before on this blog.

KEY Point: Knowing that the most commonly overlooked arrhythmia is AFlutter — suggests that the BEST way to avoid missing the diagnosis of AFlutter is simply to THINK of AFlutter whenever you have a regular SVT at a rate close to 150/minute ( in which you do not clearly see upright sinus P waves in lead II ). And a Final Tracing.

Learning points : Takotsubo can lead to cardiac arrest from ventricular arrhythmia. But there are 3 other wide beats in the tachycardia that begins with beat #6 ( = beats #7; 13,14 ). The QTc then gradually shortened over the course of several days as is usual for stress cardiomyopathy.

This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern. ECG met STEMI criteria and was labeled STEMI by computer interpretation.

Arrhythmia In simple words, arrhythmia refers to an irregular heartbeat. A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. If your heart beats too slowly, too quickly, or irregularly, an ECG will easily detect it.

I completely agree with Dr. Nossen that in this patient with new CP and sinus tachycardia with LAHB — that the T waves in each of the inferior leads are hyperacute ( ie, clearly disproportionately "bulky" given size of the QRS in these leads ). — and which other patient(s) need to be seen as soon as possible to figure out what is going on?

It can automatically detect life threatening ventricular arrhythmias and treat them, either with a shock or, sometimes by overdrive pacing. And, after the shock, if there is bradycardia, it can be covered by these two pacing electrodes, one at the tip, and one proximal to it. These are high voltage, defibrillator shock coils.

Hypokalemia was unlikely because she continued to have ventricular arrhythmia despite of correcting electrolytes.

If the patient has Abnormal Vital Signs (fever, hypotension, tachycardia, or tachypnea, or hypoxemia), then these are the primary issue to address, as there is ongoing pathology which must be identified. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.
