Orthodromic vs. Antidromic AVRT: The Loop Determines the QRS In AVRT, the circuit includes both the native conduction system and an accessory pathway (AP). The direction of impulse travel dictates the ECG morphology. 🔁 Orthodromic AVRT (Narrow QRS) • Down: AV node → His-Purkinje system (normal ventricular activation). • Back: Retrograde via the AP to the atria. • ECG: Narrow complex (unless aberrancy). ⚡ Antidromic AVRT (Wide QRS) • Down: AP directly into the ventricle (pre-excitation). • Back:

✨ Jupiter ends retrograde motion! ✨ After months of moving «backward» in the sky, Jupiter has officially ended its retrograde motion today, February 4! 🚀🔭 🌌 What is retrograde motion? If you observe a planet at the same time each day for several weeks, you’ll notice that it usually moves in one direction. But sometimes, it appears to loop backward before continuing forward—this is retrograde motion, an optical illusion caused by Earth’s movement. 🔄 Which planets are still in retrograde? - Ma

Why Mars Moves Backward - This is the retrograde motion of Mars. So why does Mars sometimes appear to move backward in the night sky? Retrograde motion is an optical illusion that happens when Earth, moving faster in its orbit, overtakes Mars. As we pass it, Mars appears to slow down, stop, and move westward temporarily — even though it's still moving forward in space. Because Mars orbits farther from the Sun than Earth does, it takes longer to complete one orbit. When Earth "laps" Mars about ev

Mercury stations to turn retrograde, moving from Sagittarius back into Scorpio by November 20th for the next Sun Cazimi. Mercury’s retrograde loop asks us to believe in what comes next and the inevitable adjustments ahead. From the expansive and mutable Sagittarius and back into the fixed and transformative realm of Scorpio, Mercury’s message asks us to take the light of Sagittarius and bring it into the Scorpionic depths, without the light being extinguished. This retrograde moves from Fire to

We created this animation to visualize the captivating retrograde motion of Saturn — a cosmic illusion that has puzzled skywatchers for millennia. In 2025, Saturn begins its retrograde on July 13 and continues this apparent backward journey through the stars until November 15. But what exactly is retrograde motion? It’s not that Saturn actually reverses its orbit — instead, it’s an optical illusion that occurs when Earth, on its faster inner orbit, overtakes the slower-moving Saturn. As we pass
