Irregular Heartbeat Count
The Irregular Heartbeat Count measures how many heartbeats appeared to fall outside the expected rhythm during your scan. An occasional irregular beat is very common in healthy people and is usually caused by stress, caffeine, deep breathing, or minor signal variation — not a heart problem. The concern rises when irregular beats appear frequently or consistently across multiple scans.
Normal range
How Vsense measures it
Vsense detects beat-to-beat timing irregularities in the rPPG signal. Beats that fall outside the statistically expected inter-beat interval are counted as irregular. This is a screening indicator — a clinical ECG is required for definitive arrhythmia diagnosis.
How it's scored
0–2 irregular beats: Normal — occasional irregularities are expected and benign. 3–5: Moderate — worth monitoring; consider rescanning in a calm state. Above 5: Frequent — discuss with a healthcare provider if this occurs consistently.
What a high reading means
A high irregular heartbeat count suggests your heart rhythm was noticeably inconsistent during the scan. Common benign causes: caffeine, anxiety, fatigue, alcohol the night before, or breathing irregularity during scanning. Medical causes (atrial fibrillation, PVCs, SVT) require clinical ECG evaluation. If you experience palpitations, dizziness, or chest discomfort alongside high counts, seek medical assessment.
What a low reading means
Zero or near-zero irregular beats is the ideal result — your heart maintained a consistent, regular rhythm throughout the scan. This is a positive sign of good cardiac electrical function.
How to improve it
Exercise
- Regular moderate aerobic exercise stabilises heart rhythm over time
- Avoid sudden intense exercise if you're prone to palpitations — warm up gradually
- Yoga and controlled breathing practices regulate autonomic tone and reduce ectopic beats
- Avoid scanning immediately post-exercise — heart rate and rhythm take 10–15 minutes to normalise
Diet
- Reduce caffeine — it's one of the most common triggers for palpitations and ectopic beats
- Increase magnesium intake (dark leafy greens, almonds, pumpkin seeds) — deficiency is a major trigger of cardiac arrhythmia
- Potassium-rich foods (bananas, avocados, sweet potato) support stable cardiac electrical function
- Stay well hydrated — dehydration disrupts electrolyte balance and can trigger irregular beats
- Avoid alcohol — it directly irritates cardiac electrical tissue and is a leading cause of paroxysmal atrial fibrillation
Lifestyle
- Manage stress — adrenaline surges are a primary trigger for ectopic heartbeats
- Get sufficient sleep — sleep deprivation disrupts cardiac autonomic regulation
- Avoid stimulants (energy drinks, excessive coffee) if you're prone to palpitations
- Scan in a relaxed, calm state — anxiety during scanning often shows up as rhythm irregularities
Natural remedies
- Slow diaphragmatic breathing immediately before and during scanning reduces autonomic irregularity
- Magnesium glycinate (300–400mg before bed) is the most commonly recommended supplement for cardiac rhythm stability
- Reducing alcohol and caffeine simultaneously is the fastest lifestyle change for improving heart rhythm regularity
- The Valsalva manoeuvre (bearing down gently for 10–15 seconds) can terminate some types of rapid irregular rhythm — but consult a doctor if you use this regularly
Frequently asked questions
Are irregular heartbeats dangerous?
Occasional benign ectopic beats (PVCs or PACs) are extremely common — affecting most adults at some point. They are usually harmless. Concern arises when they are frequent (>5 per minute consistently), symptomatic (causing dizziness or fainting), or part of a sustained rhythm disturbance.
What causes my heart to skip a beat?
The most common causes are benign: caffeine, alcohol, fatigue, dehydration, anxiety, and adrenaline surges. The 'skipped beat' feeling is usually an ectopic (early) beat followed by a compensatory pause — the heart didn't actually skip, it beat early and then waited.
Should I see a doctor about heart rhythm irregularity?
See a doctor if: you regularly get high counts across multiple scans, you experience associated symptoms (dizziness, chest pain, fainting, sustained palpitations), or if you have known heart disease, diabetes, or hypertension. A 12-lead ECG or Holter monitor gives a definitive picture.
Can anxiety cause irregular heartbeats?
Yes — anxiety and panic are among the most common causes. Adrenaline released during anxiety directly triggers ectopic beats in many people. Managing anxiety often dramatically reduces palpitation frequency.
Does caffeine actually cause palpitations?
Yes, it's one of the most consistently reported and validated triggers. Caffeine raises adrenaline, increases heart rate, and lowers the threshold for ectopic beats. Reducing caffeine is often the single most effective lifestyle change for people prone to palpitations.
