Clinical Cases
AF Phenotyping?
Persistent or Paroxysmal?
- Patient received as “Persistent AF” via standard ECG and 24-hour Holter
Yet when wearing Rhythm30, found 2 days of sustained AF was terminated by a 9.5s pause, and back to NSA (normal sinus arrhythmia)
- Female,70,repeated symptoms of heart racing
- AF occurred only on 8th day between 2:53am and 5:03am
Post AF Ablation Complaints
To relieve patient’s concerns
- Patient well educated on AF ablation, complaints on continued symptoms even after the surgery
- Wearing Rhythm30 for 14 days, captured all moments when he felt symptoms. No AF related
- Patient switched for psychological consultation
Capturing the Fainting Moment
To diagnose what causes a young female patient’s fainting
- Female,21,Professional basketball player, With syncope history
- Went two hospitals but no specific findings.
- Wearing Rhythm30, on 7th day 11:35am patient feeling dizziness, associated with a 5s pause
Other Cardiac Arrhythmias - VT
Syncope & Implantable Device Follow-Up
- Rhythm30 captured short VT on 7th day Patient wearing Rhythm30 & GE 12-lead Holter simultaneously
- Patient complained symptoms after implantable treatment (ICD-Pacing) but without any device discharge Wearing Rhythm30 to find out the reason
Capturing the Syncope Moment
To diagnose what causes a senior female patient’s Syncope
- Female,63,repeated syncope
- Rhythm 30 captured syncope event on 6 th day
- Accelerometer signal confirmed a fell-down reported by the patient
To diagnose what causes a senior male patient’s Syncope
- Male,66,unknown syncope
- Rhythm30 captured a pause of 16 sec on 3rd day during sleep
Capturing Dizzy Moment
To diagnose what’s the cause
- Male,41,complaint of dizziness.
- Rhythm30 captured II°II AV block on 22nd day during sleep.
Opportunistic Screening on acute ST elevation
To capture abnormal ECGs
- Male,50+
- Rhythm30 captured two bursts of ST elevation, each lasting 3 min without symptoms
- Confirmed later with treatment of stents
Caution:
This shall NOT be the primary indication for use of Rhythm30
Stroke & AF
To screen AF for stroke patient
- Male,57,TIA (transient ischemic Attack)
- Rhythm30 captured An episode of AFib, on 20th day
- AFib Lasted for 1 hour 3 min 18 sec during sleep
High Risk Indicators for Fatal Cardiac Arrhythmias
LOW Heart Rate Variability
- Female,67
- Rhythm30 captured Ventricular arrhythmias and Low HRV SDNN < 50
