For cardiology practices
The warning signs
show up a week early.
If someone is watching.
Weight climbs, sleep goes upright, the six-minute walk shortens - days before the patient calls. Ziva watches every enrolled cardiac patient daily and escalates the pattern to your team while it's still manageable in clinic.

"Three-point-eight pounds in seventy-two hours with new orthopnoea and a missed diuretic yesterday. Rapid weight gain plus new orthopnoea together is the classic pre-decompensation pattern — flagged for same-day review."

The gap
The data you need arrives
after the admission.
Cardiovascular disease is the best-suited specialty in medicine for continuous monitoring - the signals are objective, quantitative and available daily - and most cardiology panels are still managed on quarterly snapshots.
Heart failure readmissions
Fluid accumulation is measurable days before symptoms force a call. Without daily weights reaching your team, that window is spent unmonitored.
Uncontrolled hypertension
Office readings are noisy and infrequent. Titration decisions get made on two data points a quarter while the real average sits somewhere else.
Adherence you can't see
Diuretic, anticoagulant and antihypertensive adherence drives outcomes more than regimen choice - and is invisible between visits.
The continuous care experience
A daily cardiovascular
record for every patient.
The continuous care experience means each cardiac patient has a daily point of contact and a daily data record. Isabella handles the routine; your team sees the deviations.
01
Morning weight and BP
Connected scale and cuff transmit automatically. Standardised timing, no manual logging, no transcription error.
02
Symptom check-in
Dyspnoea, orthopnoea, oedema, chest discomfort, exercise tolerance and fatigue captured daily in plain language.
03
Isabella correlates
Weight trajectory against symptom onset against adherence - the sequence, not just the values.
04
Coaching between visits
Sodium, fluid, activity pacing, medication timing and rehab adherence reinforced daily.
05
Escalation with the sequence
Your team gets the trend, the symptoms and the adherence history together, ready for a titration or a same-day visit.
Because contact is daily and documented, RPM and CCM time thresholds are met as a by-product of care rather than as a separate administrative exercise.
How Ziva helps
What Ziva does
for a cardiology practice.
Objective daily physiology plus subjective daily symptoms plus adherence - the three inputs that determine whether a cardiac patient stays out of hospital.
Heart failure
Daily weight monitoring
The earliest reliable decompensation signal, trended against the patient's dry weight and escalated on trajectory, not a single threshold.
Hypertension
Home BP averages
Titration decisions based on a rolling home average rather than an office reading taken after a walk from the car park.
Symptoms
Symptom trajectory
Orthopnoea, oedema and exercise tolerance tracked daily so decline is a curve, not a surprise.
Adherence
Medication adherence
Each medication tracked separately - a missed diuretic and a missed statin mean very different things clinically.
AFib
Rhythm monitoring
Apple Watch irregular rhythm notifications and on-demand ECG for AFib patients, correlated with symptoms and medication timing.
Recovery
Rehab & recovery coaching
Patients recovering from a heart attack or procedure get daily coaching through rehab, with adherence visible to your team.
Impact
Outcomes that matter
in cardiovascular care.
Earlier detection changes the setting of care - clinic instead of emergency department, titration instead of admission.

The full care journey
From enrollment
to escalation - Ziva runs every step.
No new staff, no parallel system to learn. Your team sees the alert queue and the chart - Ziva runs everything in between.
Trajectory, not thresholds
A 3 lb gain over two days is not the same event as the same gain over three weeks. Alerts reflect that.
Device quality
Validated, cellular-connected scales and BP cuffs. No phone pairing, no Bluetooth support calls.
Cross-condition
Most cardiac patients also carry diabetes, CKD or sleep apnoea. Protocols run together on one patient record.
Time logs for billing
Every monitoring minute captured and exportable - see the reimbursement section below.
Proof
Continuous contact that
changed the outcome.
Conditions covered
Cardiovascular and comorbid conditions.
Cardiac patients rarely carry one diagnosis. Ziva runs concurrent protocols on the same record.
Reimbursement
Cardiology is where
RPM economics are strongest.
Device-based physiologic monitoring is squarely what RPM was written for, and most cardiac patients also meet CCM's two-chronic-condition requirement. Both programs can run on the same patient in the same month where the time is separately documented.
RPM — 99453 / 99454 / 99457 / 99458
Device-based physiologic monitoring, 16+ transmission days per month
99453One-time setup & patient education — ~$19
99454Device supply + daily transmission — ~$46/mo
99457First 20 min interactive care management — ~$48
99458Each additional 20 min — ~$39
CCM — 99490 / 99439
Patients with two or more chronic conditions expected to last 12+ months
99490First 20 min clinical staff time / month — ~$62
99439Each additional 20 min — ~$47 (up to 2×)
Complex CCM — 99487 / 99489
60+ minutes/month and moderate-to-high complexity medical decision making
99487First 60 min / month — ~$130
99489Each additional 30 min — ~$67
Ziva's time logs, monitoring records and monthly reports supply the documentation these codes require. Confirm eligibility and rates with your billing team and MAC.

Get Started
Start with your
heart failure cohort.
Most cardiology practices begin with 40–60 heart failure patients, where the readmission economics are clearest, then expand into hypertension.

Questions
Cardiology FAQ
Generally yes, provided the time and activities are separately documented and not double-counted. RPM covers device-based physiologic monitoring and the associated management time; CCM covers comprehensive care management for two or more chronic conditions. Ziva logs the two time streams separately for exactly this reason. Confirm with your billing team and MAC.
A validated cellular-connected weight scale and, where indicated, a blood pressure cuff and pulse oximeter. Devices transmit automatically over cellular - no smartphone, WiFi setup or Bluetooth pairing required, which materially improves adherence in older cardiac populations.
For AFib, we recommend an Apple Watch for its irregular rhythm notifications and on-demand ECG, alongside the connected BP cuff for home pressure trends. Episode frequency and duration are logged alongside symptoms and medication timing on the same record.
Per patient, from the provider portal. You set dry weight, BP targets, weight-gain trajectory rules, and symptom escalation criteria consistent with your protocols. Isabella evaluates trajectory and symptom co-occurrence rather than firing on a single out-of-range value, which is what keeps alert volume clinically useful.
Ziva's core inputs are external - weight, blood pressure, oxygen saturation, symptoms and adherence - and are designed to complement rather than duplicate CIED remote monitoring. Where your practice already reviews device telemetry, Ziva adds the behavioural, symptomatic and adherence layer that telemetry doesn't capture.
Typically 3–6% of an enrolled cohort flags on any given day, and the queue is ranked. Practices with 120 enrolled patients generally spend 20–30 minutes on the morning review. Alert sensitivity is configurable if you want it tighter or looser.
