Bigeminy & Trigeminy Detection
The only app that detects bigeminy and trigeminy patterns in Apple Watch ECG recordings. HeartLab identifies these important PVC patterns automatically.
What Are Bigeminy and Trigeminy?
Bigeminy and trigeminy are specific patterns of premature ventricular contractions (PVCs). In bigeminy, every other heartbeat is a PVC โ creating an alternating pattern of normal beat, PVC, normal beat, PVC. In trigeminy, every third heartbeat is a PVC โ normal, normal, PVC, normal, normal, PVC. These patterns are clinically significant because they indicate a higher PVC burden than isolated PVCs and may affect cardiac output. Recognizing these patterns helps cardiologists assess heart rhythm stability and determine whether treatment is needed.
How HeartLab Detects These Patterns
HeartLab goes beyond simple PVC counting. After identifying each PVC in your Apple Watch ECG recording, HeartLab analyzes the beat-to-beat sequence to detect repeating patterns. The algorithm identifies bigeminy (1:1 pattern), trigeminy (2:1 pattern), and quadrigeminy (3:1 pattern). This pattern recognition is unique to HeartLab โ no other consumer ECG app for Apple Watch offers this level of analysis. The detection happens entirely on your device, ensuring complete privacy.
Why Pattern Detection Matters
Isolated PVCs are usually harmless, but organized patterns like bigeminy and trigeminy can indicate more significant cardiac rhythm disturbances. By detecting these patterns, HeartLab helps you provide your cardiologist with detailed, actionable data that goes beyond what a standard Apple Watch ECG shows. You can track whether patterns occur consistently, identify triggers, and monitor the effectiveness of any treatment your doctor recommends.
FAQ
What does bigeminy feel like?
Bigeminy may feel like a skipped beat or fluttering in the chest every other heartbeat. Some people feel palpitations, while others don't notice them at all. HeartLab can detect bigeminy even when you don't feel symptoms.
Is bigeminy dangerous?
Occasional bigeminy is usually not dangerous. However, persistent bigeminy with a high PVC burden may reduce cardiac output. HeartLab helps you monitor the frequency and share data with your cardiologist.
Can any other app detect bigeminy or trigeminy?
HeartLab is one of the only consumer apps that automatically detects bigeminy and trigeminy patterns in Apple Watch ECG recordings. Most other ECG apps only count total PVCs without analyzing patterns.
What's the difference between bigeminy and trigeminy?
In bigeminy, every other beat is a PVC (alternating pattern). In trigeminy, every third beat is a PVC. Both are patterns of premature ventricular contractions detected by HeartLab.
