Cardiac Conduction Timelines (Post-SA Node)
This electrophysiological map illustrates the precise, millisecond conduction sequence of the human cardiac impulse. Originating at the SA node (0.00s), activation traverses the atria, pauses at the AV node (~0.09s), and rapidly propagates via the His-Purkinje system to achieve coordinated ventricular depolarization (0.16-0.22s).⚡📈

🚨 Hyperkalemia : ECG Essentials 🚨
✔️ HyperK: Peaked T → Sine wave → Cardiac arrest.
Watch how increasing potassium levels affect the heart. As K+ rises, notice these ECG changes:

Flattened P Wave: Impaired atrial depolarization.
Widened QRS Complex: Delayed ventricular depolarization.
These changes can lead to severe arrhythmias and potentially cardiac arrest if not treated promptly.

Aneurysm Types
Fusiform ↔️: Symmetrical dilation, often abdominal aorta.
Saccular 🎈: One-sided bulge, "berry" shape.Dissecting 🩸: Tear in inner layer, false lumen.
False 🩹: External clot, appears as bulge.

🎯Recognize these 11 high-risk ECG patterns suggestive of acute occlusion, which require urgent intervention:

· Wellens Syndrome (A: Biphasic T-waves; B: Deeply inverted T-waves)
· de Winter T-waves (Upsloping ST depression & tall T-waves)
· Posterior STEMI (Horizontal ST depression V1-V4, tall R wave V2)
· Hyperacute T-waves (Tall, broad, asymmetrical T-waves)
· Sgarbossa Criteria (in LBBB/Paced Rhythm)
· Left Ventricular Hypertrophy Mimic (STE >25% S-wave)

Early recognition of these patterns is critical for timely reperfusion.

Tetralogy of Fallot (TOF)
Two Patients, Two Different Diseases
The anatomic variation—from mild pulmonary stenosis to pulmonary atresia or absent pulmonary valve syndrome—means two patients with the diagnosis of "TOF" can have:

· Radically different imaging findings (echo, CT, MRI).
· Dramatically different clinical behavior (cyanosis, heart failure, airway compression).
· Fundamentally different surgical plans and long-term outcomes.

📉🌟 Main Characteristic ECG Changes in Electrolyte Imbalances: Potassium and Calcium Levels:

Hypokalemia (Low Potassium): Prominent U waves (best seen in the precordial leads V2-V3)📉

Hyperkalemia (High Potassium): Peaked T waves 📈

Hypocalcemia (Low Calcium): Prolonged QT interval 🔍

Hypercalcemia (High Calcium): Shortened QT interval 📏

The heart-kidney connection is crucial! 💔↔️🧠 This is an excellent breakdown of Cardiorenal Syndrome – a pathophysiological disorder where dysfunction in one organ acutely or chronically induces dysfunction in the other.

This infographic beautifully summarizes:
🔹 The 5 classification types
🔹 Key etiological mechanisms
🔹 Clinical signs of acute/chronic heart failure
🔹 The self-perpetuating cycle of hemodynamic and neurohormonal interactions
