Cardiology Memes

When your cardiology pickup lines are too specific for Tinder. The AV node delay is crucial for proper heart function - it ensures the atria finish contracting before ventricles start, maximizing cardiac output. And that QT interval? It's measuring ventricular depolarization and repolarization time. Nothing says romance like perfectly timed electrical cardiac cycles. Next time just try "you make my heart skip a beat" instead of sounding like you're preparing for boards.

The medical irony that would make any cardiologist snort coffee through their nose! When blood flow returns after a heart attack (top image: school bus calmly crossing tracks), your cells should be celebrating, right? WRONG. Instead, they're getting absolutely wrecked by free radicals in what we call "reperfusion injury" (bottom image: train demolishing bus). It's like inviting the fire department to your house fire only to have them flood your basement. Your body's rescue mission becomes its own disaster movie. The ultimate biological plot twist that keeps cardiovascular researchers employed for decades!
