Cardiac pain for 8 h

Cardiac pain for 2day

#STD_in_right_vent_hypertrophy
right ventricular hypertrophy (RVH) causes ST depression and T-wave inversion in the right precordial leads V1-3.

#STD_IN_SVT:_
Supraventricular tachycardia (e.g. AVNRT) typically causes widespread horizontal ST depression, most prominent in the left precordial leads (V4-6).
This rate-related ST depression does not necessarily indicate the presence of myocardial ischaemia, provided that it resolves with treatment

#ST_depression_in_hypokalemia:_
Hypokalaemia causes widespread downsloping ST depression with T-wave flattening/inversion, prominent U waves and a prolonged QU interval

#Morphology_of_ST_Depression
ST depression can be either upsloping, downsloping, or horizontal.
#Horizontal or #downsloping ST depression ≥ 0.5 mm at the J-point in ≥ 2 contiguous leads indicates myocardial ischaemia (according to the 2007 Task Force Criteria).
#Upsloping ST depression in the precordial leads with prominent De Winter T waves is highly specific for occlusion of the LAD.
Reciprocal change has a morphology that resembles “upside down” ST elevation and is seen in leads electrically opposite to the site of infarction.
#Posterior MI manifests as horizontal ST depression in V1-3 and is associated with upright T waves and tall R waves.

#STD_in_digoxin_treatment:_
Treatment with digoxin causes downsloping ST depression with a “sagging” morphology, reminiscent of Salvador Dali’s moustache
