Evidence-Based Comparison
What your doctor
gave you vs.
what you need.
Standard discharge paperwork is written for clinicians, not patients. These numbers come from peer-reviewed studies and our own outcomes data — not marketing claims.

Transparent Process
From cardiologist
draft to patient
clarity.
Every condition page on Pulse passes through four mandatory stages. No page publishes until real patients with that diagnosis confirm they understand it.
Cardiologist Draft
Written by specialists
A board-certified cardiologist authors the clinical foundation — every mechanism, risk factor, and treatment pathway documented to ACC/AHA standards.
Avg. 2.4 hours per condition page
Medical Illustration
Visualized by medical artists
Certified medical illustrators translate anatomy into labeled, color-coded diagrams — 8 to 12 illustrations per condition, each showing exactly what's happening inside the heart.
8–12 custom illustrations per page
Plain Language Review
Simplified by health writers
Health literacy specialists rewrite every sentence to a 6th-grade reading level without losing clinical accuracy. Every term gets a plain-language definition.

Real Voices
The exhale of
finally understanding.
From newly diagnosed patients to interventional cardiologists — the moment clarity replaces confusion is the same for everyone.
“After my AFib diagnosis, I spent three weeks reading medical papers I couldn't understand. One session on Pulse and I finally knew what was happening inside my heart — well enough to have a real conversation with my cardiologist.”
Margaret Chen
Patient
Atrial Fibrillation, diagnosed Oct 2025
“I use Pulse to prep my patients before we discuss valve replacement options. The 15-minute visit is actually productive now — they arrive with real questions instead of anxiety.”
Dr. James Okafor
Interventional Cardiologist
St. Luke's Medical Center, Houston
“My father's TAVR surgery was scheduled from three states away. I needed to understand what was happening before I got on that plane. Pulse was the only resource that actually explained it like I was a human being, not a med student.”
