Is Your EKG App Working? 5 Ways to Check
You can check if your EKG app is working properly by comparing readings with medical devices, testing it during different activities, and monitoring for consistent waveform patterns. Most EKG apps…

How to Identify SVT (Supraventricular Tachycardia)
SVT (Supraventricular Tachycardia) appears as a heart rate above 150 beats per minute with narrow QRS complexes on an ECG, often starting and stopping suddenly. You can identify SVT by…

What Causes a Flat Line on EKG? (Not Always Death)
A flat line on EKG can result from loose electrodes, electrical interference, or machine problems – not just cardiac arrest. Technical issues like disconnected leads or patient movement cause most…

Can a Low Battery Affect EKG Accuracy?
Yes, a low battery can affect EKG accuracy by causing signal distortion, incomplete readings, and device malfunctions that compromise your heart rhythm measurements. Your EKG device needs consistent power to…

Athlete vs. Non-Athlete EKG: What is Normal?
Athletes typically show lower resting heart rates, stronger electrical signals, and structural adaptations on EKG readings that would be considered abnormal in non-athletes. Normal EKG patterns for athletes include heart…

What is a PAC? Premature Atrial Contractions
A PAC (Premature Atrial Contraction) is an extra heartbeat that starts in your heart’s upper chambers before your regular heartbeat is due. These early beats are usually harmless and feel…

How to Identify Sinus Arrhythmia on Your EKG
Sinus arrhythmia appears on your EKG as a heart rhythm that speeds up when you breathe in and slows down when you breathe out, creating an irregular but predictable pattern….

EKG Signs of Wolff-Parkinson-White (WPW)
Wolff-Parkinson-White syndrome creates a distinctive delta wave pattern on EKG readings, appearing as a slurred upstroke at the beginning of the QRS complex. You can identify WPW by looking for…

What is the U Wave? Rare EKG Findings Explained
The U wave is a small deflection on an EKG that appears after the T wave, representing the final phase of ventricular repolarization. You’ll typically see U waves in leads…

Can an EKG Detect Ectopic Beats? (PVCs/PACs)
Yes, an EKG can detect ectopic beats including PVCs (premature ventricular contractions) and PACs (premature atrial contractions). These irregular heartbeats show up as distinct patterns on EKG tracings that doctors…
