ST-Elevation Myocardial Infarction Complicated by Cardiogenic Shock

…prolonged, produces multiorgan dysfunction and death. In the setting of ST elevation myocardial infarction (STEMI), cardiogenic shock most commonly reflects severe left ventricular (LV) dysfunction…

Supraventricular and intraventricular conduction defects in myocardial ischemia and infarction

…is most likely to be defect because it is most sensitive to myocardial ischemia. Note that isolated fascicular blocks are uncommon in acute myocardial infarction…

Left bundle branch block (LBBB) in acute myocardial infarction: the Sgarbossa criteria

Conduction defects ECG Myocardial ischemia and infarction Left bundle branch block (LBBB) in acute myocardial infarction (AMI): clinical implications & Sgarbossa criteria Contrary to right bundle…

Pharmacologic agents in myocardial perfusion imaging

…pronounced in healthy arteries, which can dilate more than stenotic arteries, which are already dilated. This results in flow heterogeneity and perfusion defects in areas…

Digoxin - ECG changes, arrhythmias, conduction defects & treatment

…conduction defects and waveform changes Digoxin may be used in patients with heart failure, atrial fibrillation, atrial flutter, and in selected cases of paroxysmal supraventricular…

Other ECG changes in ischemia and infarction

…QRS configurations are also indicate of previous myocardial infarction. New conduction defect Myocardial infarction/ischemia may be complicated with conduction defects (discussed in separate article).

The left ventricle in myocardial ischemia and infarction

…the fact that the Purkinje fibers run through the endocardium. It is likely that conduction defects would have been more common in myocardial ischemia otherwise.

Second-degree AV block: Mobitz type 1 (Wenckebach) & Mobitz type 2 block

Conduction defects ECG Second degree AV block: ECG criteria, clinical characteristics & management In this chapter, the focus will be on second degree atrioventricular (AV) block…

Right bundle branch block (RBBB): ECG, criteria, definitions, causes & treatment

Conduction defects ECG Right bundle branch block (RBBB) Right bundle branch block (RBBB) is due to an anatomical or functional dysfunction in the right bundle…

Intraventricular conduction delay: bundle branch blocks & fascicular blocks

…of the conduction system is dysfunctional. Conduction defects in the bundle branches and/or fascicles cause characteristic ECG changes. The type of ECG changes that…
