ECG From Scratch #29: Axis Deviation in Seconds You don't always need to calculate the exact QRS axis. For beginners, start with one simple question: (Is the QRS axis normal, leftward, or rightward?) ➡️ You can often answer this by looking at just Lead I and Lead II. The quick method Look at the overall QRS polarity in I and II. 1️⃣ Lead I positive + Lead II positive = Normal axis 2️⃣ Lead I positive + Lead II negativ: Left axis deviation (LAD) 3️⃣ Lead I negative + Lead II positive: Right axis deviation (RAD) 4️⃣ Lead I negative + Lead II negative: Extreme axis deviation Also called an indeterminate or northwest axis in some ECG terminology. This isn't a substitute for precise axis calculation when needed, but it is an excellent first-pass screening method. And remember: Axis interpretation starts with polarity, not mathematics. 📸 Courtesy of:

Echo From Scratch | Post #16 Parasternal Long-Axis View: Your First Major Window The parasternal long-axis view, or PLAX, is one of the foundational views in transthoracic echocardiography. The patient is generally positioned in the left lateral decubitus position, with the transducer placed near the left sternal border, usually around the 3rd or 4th intercostal space. The goal is to obtain a plane that displays the LV long axis and the aortic and mitral valves. A good PLAX view typically shows: 🫱Right ventricular outflow tract 🫱Left ventricle 🫱Left atrium 🫱LV outflow tract 🫱Aortic valve 🫱Aortic root and prox ascending aorta 🫱Mitral valve The standard PLAX plane provides an important anatomical relationship between the aortic and mitral valves.
