This hemodynamic sign of tamponade reflects exaggerated ventricular interdependence and is defined by a ≥10 mmHg inspiratory drop in systolic blood pressure.
pulsus paradoxus
This mechanism is most responsible for the no-reflow phenomenon post-PCI.
Microvascular obstruction from distal embolization
This ECG feature, not epsilon waves, is the most common abnormality in ARVC.
T-wave inversions in V1–V3
Prasugrel blocks:
P2Y12
“Follow up in sudden death clinic. Next available. Plenty of openings.”
Manish Assar

This pericardial disease entity is characterized by normal pericardial thickness, abnormal myocardial-pericardial coupling, and responds better to anti-inflammatory therapy than surgery.
transient constrictive pericarditis
This landmark trial demonstrated no mortality benefit of PCI over optimal medical therapy in stable CAD with moderate-to-severe ischemia.
ISCHEMIA
This ECG lead placement modification increases sensitivity for detecting Brugada patterns.
high right precordial lead placement (V1–V2 in the 2nd or 3rd intercostal space)
Ivabradine blocks:
Funny channels
“Oh you’re blind? Well, I look like Brad Pitt”
Alan Donsky

This ECG finding in acute pericarditis reflects atrial involvement and is most specific when present.
PR-segment depression
In STEMI patients with multivessel disease without shock, complete revascularization is recommended during this timeframe.
during index hospitalization or staged PCI
This pharmacologic agent is recommended for provocative testing to unmask Brugada syndrome in equivocal ECGs.
ajmaline (Procainamide or flecainide acceptable alternatives)
Bempedoic acid blocks:
ATP citrate lyase
(enzyme upstream of HMG-CoA reductase)
“I took her to the lab, because resuscitation was going really well…after over an hour.”
Subhash Banerjee

This cytokine is specifically targeted by anakinra and rilonacept in colchicine-resistant recurrent pericarditis.
Interleukin 1 (IL-1)
An IVUS MLA below this threshold in the left main generally warrants revascularization.
<6.0 mm²
This nuclear envelope protein mutation produces a cardiomyopathy marked by AV block, atrial fibrillation, and ventricular tachyarrhythmias years before LV dilation, distinguishing it from desmosomal disease.
LMNA
Zilebesiran blocks:
Angiotensinogen (siRNA therapy that blocks hepatic production of angiotensinogen)
“Did you find this strip in the trash?”
Jay Franklin

This X-linked lysosomal storage disorder can present with recurrent pericardial effusions and constrictive physiology, low-voltage ECG, and later restrictive cardiomyopathy, frequently leading to misdiagnosis as idiopathic pericardial disease.
Fabry Disease
In NSTEMI, early invasive strategy (<24 hours) is specifically recommended for patients with this GRACE score threshold.
GRACE score >140
This specific genotype of Long QT syndrome is most strongly associated with arrhythmic events triggered by exercise and swimming (MUST HAVE BOTH SYNDROME TYPE AND GENETIC MUTATION).
LQT1 (KCNQ1 mutation)
Vupanorsen blocks:
ANGPTL3 (regulator of triglyceride metabolism but had development halted due to hepatic toxicity)
“symptoms are chill….other than death”
Renato Quispe
