Aslan Health HRV Guide
A physician's seven-page guide to heart rate variability: what HRV is, how to track it, a 7-day tracker, and habits that build lasting resilience.
Your wearable reports a number every morning. This seven-page guide helps you read it as useful context rather than a verdict. It accompanies the three-part Aslan Health podcast series on heart rate variability: Reveal, Reset, and Renew.
What is inside
What HRV is and is not: what a higher or lower reading may accompany, and why your own baseline matters more than anyone else's number.
Five rules for a cleaner baseline, a plain-language look at how devices differ (metric, sensor, sampling window, algorithm), and a proportionate response to a low reading.
A printable 7-day HRV reset tracker with columns for sleep, training, alcohol, stress, and context.
Six pillars for renewing resilience (sleep, breath, movement, nourishment, soul and stress, and recovery context) and a 30-day practice.
Clear signs to contact a clinician or seek urgent care, with Scripture from 2 Timothy 1:7, Psalm 1:3, and Isaiah 26:3.
The guidance draws on the 1996 Task Force standards of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology, along with systematic reviews on wearable accuracy and slow breathing. Sources are listed in the guide.
Consumer wearables can miss or misclassify rhythm abnormalities. New palpitations or a wearable alert for an irregular rhythm deserve a conversation with your clinician. Chest pain, fainting, or severe shortness of breath need urgent care.
Use alongside the Sleep Hygiene Guide and the Aslan Health Sleep Renew Plan, and listen to the companion episodes: Part 1, Part 2, and Part 3.
