AliveCor Personal ECG Monitors

AliveCor puts clinical-grade heart rhythm monitoring in the palm of your hand. For anyone managing atrial fibrillation, tracking palpitations, or following a cardiologist's recommendation to keep an eye on heart rhythm between appointments, AliveCor's KardiaMobile technology turns a smartphone into a personal ECG recorder—no wires, no chest leads, no clinic visit required.

The AliveCor Kardia Mobile ECG (4th Generation, AC-009-UA-C) works with both iPhone and Android through the free Kardia app. You place two fingers on the sensor pads, and in about 30 seconds it captures a medical-grade single-lead ECG and screens for atrial fibrillation, bradycardia, tachycardia, and normal sinus rhythm. Recordings can be saved, emailed as a PDF, or shared directly with your doctor—making it genuinely useful for those "I felt a flutter last Tuesday" moments that never seem to happen in the exam room.

A common question from first-time buyers is whether a device this small is trustworthy. KardiaMobile is FDA-cleared and used by patients and clinicians alike; its readings are designed to be reviewed alongside professional care, not to replace it. The pocket-sized recorder pairs with your phone via a sensor pad rather than Bluetooth on this model, and it runs on a standard coin-cell battery, so there's nothing to charge before you can take a reading.

It's a practical tool for patients tracking a diagnosed arrhythmia, caregivers monitoring an older parent, or anyone whose symptoms come and go. To build out a complete home heart-health kit, explore related equipment in our Blood Pressure Monitors and broader Diagnostics collections.
