ECG Changes in Intracranial Hemorrhage

All About Cardiovascular System and Disorders

In that study commonest ECG abnormalites were QTc prolongation followed by brady/tachycardia and then ST segment deviations [3]. Cerebrovascular damage can cause cardiac arrhythmias related to disinhibition of right insular cortex with resulting increased sympathetic tone. 2009 Nov;40(11):3478-84. Epub 2009 Aug 27.

Precordial ST depression. What is the diagnosis?

Dr. Smith's ECG Blog

Notice there is tachycardia. I have warned in the past that one must think of other etiologies of ischemia when there is tachycardia. In this case, the patient had failed to take his atenolol in the AM and was having reflex tachycardia in addition to ACS. Blackwell Publishing 2009. BP was 160/100. younger smoker).

What do you think of this "Ventricular Bigeminy"?

Dr. Smith's ECG Blog

Another way that WPW can be concealed is in the very rare (~15% of all WPW patients) retrograde-only conduction, in which the accessory pathway ONLY allows retrograde conduction, which obviously wouldn't show a delta wave on sinus EKG but still predisposes the patient to re-entry tachycardias.

A young lady with wide complex tachycardia. My first time actually making this diagnosis de novo in real life in the ED!

Dr. Smith's ECG Blog

She was awake, alert, well perfused, with normal mental status and overall unremarkable physical exam except for a regular tachycardia, possible rales at both bases, some mild RUQ abdominal tenderness. Thus, I believe it is a regular, monomorphic, wide complex tachycardia. Or it could simply still be classic VT. What is the Diagnosis?

Emergency Department Syncope Workup: After H and P, ECG is the Only Test Required for Every Patient.

Dr. Smith's ECG Blog

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. The most recent and probably best study is this: Canadian Syncope Arrhythmia Risk Score. Arch Intern Med 2009 Jul 27; 169:1262.
