Bedside cardiac ultrasound showed moderately decreased LV function. EKG with paced complexes shown below shows much narrower QRS complex and echocardiogram showed improved LV systolic function primarily due to improvement in LV dyssynchrony. (J Even with tachycardia and a paced QRS duration of ~0.16 She was intubated.

He was rushed by residents into our critical care room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock. He had this ECG recorded. Are the lungs clear?

On arrival, lung ultrasound confirmed pulmonary edema (B lines). Conventional algorithm interpretation: SINUS TACHYCARDIA ABNORMAL RHYTHM ECG Confirmed by over-reading physician Transformed ECG by PM Cardio: PM Cardio interpretation: OMI with Low Confidence Dr. This is proximal LAD Occlusion until proven otherwise.

Echocardiogram showed severe RV dilation with McConnell’s sign and an elevated RVSP. Cardiac Ultrasound may be a surprisingly easy way to help make the diagnosis Answer: pulmonary embolism. Now another, with ultrasound. and tachycardia, 1.8. The patient was upgraded to the ICU for closer monitoring. What is the Diagnosis?

There is sinus tachycardia. Sinus tachycardia, which exaggerates ST segments and implies that there is another pathology. I have always said that tachycardia should argue against acute MI unless there is cardiogenic shock or 2 simultaneous pathologies. Here is that ECG: What do you think? No wall motion abnormality.

Interpretation: There is sinus tachycardia, with right bundle branch block (RBBB). Hemodynamic instability in trauma is usually due to bleeding, but if ultrasound shows poor contractility, then this may be due to cardiac contusion. She was pulseless, with a narrow complex tachycardia on the monitor. She was intubated.

He had diffuse crackles on exam and B-lines on chest ultrasound, and chest x-ray also confirmed pulmonary edema. Here is his ED ECG: There is sinus tachycardia. The amount of ST elevation and depression is slightly less than on the ECG above, but there is also no tachycardia, which tends to exaggerate ST deviation.
