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
