How to Use This Wiki

If you're new to cardiac rehab, start here:

If you want... Start with...
Understand the rehab roadmap Cardiac Rehabilitation Phases — Phase I through IV
Calculate your exercise intensity Aerobic Exercise Prescription — Karvonen formula, RPE, GXT
Know how much exercise is enough Exercise Volume for Secondary Prevention — 1500 → 2200 kcal/wk targets
Choose a safe modality Low-Impact Cardio Modalities — 5 modalities compared
Start resistance training safely Resistance Training Entry Timeline — MI/PCI/CABG timelines
Avoid dangerous breath-holding Valsalva Maneuver — four hemodynamic phases, correct breathing
Practice yoga or tai chi safely Yoga for Cardiac Recovery or Tai Chi vs Yoga
Understand your risk class Risk Stratification — AACVPR low/moderate/high criteria

Key Clinical Numbers at a Glance

⌂ Concepts — the "what" and "why"

Page Summary
Cardiac Rehabilitation Phases Four-phase framework: inpatient → subacute → intensive → lifelong maintenance
Aerobic Exercise Prescription HRR, Karvonen formula, Borg RPE, duration-first progression rule
Exercise Volume for Secondary Prevention 1000/1500/2200 kcal/wk tiers, MET-minute formula, mortality correlation
Low-Impact Cardio Modalities Five modalities compared (rowing, swimming, walking, cycling, bands) + sample schedule
Resistance Training Entry Timeline MI/PCI/CABG timelines, sternal precautions, hemodynamic safety, Rx guidelines
Valsalva Maneuver Four-phase hemodynamic response, absolute contraindications, correct breathing technique
Yoga for Cardiac Recovery 5 contraindicated posture categories, 5 heart-safe alternatives, breathwork warnings
Static Stretching 15–60s holds for cool-down; never combined with Valsalva
Dynamic Flexibility Active ROM through full joint path; preferred warm-up protocol
Mobility Positions End-range joint positions for active control, capsule health, and positional breathing
Isometric Holds Static strength-endurance holds for BP management, core stability, and functional leg strength
Risk Stratification AACVPR low/moderate/high criteria — determines telemetry, GXT, and supervision needs

⌂ Entities — the specific tools

Page Type Key Use
Rowing Ergometer 85% muscle engagement; Phase II → IV
Recumbent Cycling Stationary bike Back-supported; Phase II preferred for balance-impaired
Yoga Mind-body Phase III–IV only; contraindicated postures listed
Tai Chi Mind-body Phase IV; strong fall prevention, zero Valsalva risk
Swimming Aquatic Hydrostatic venous return; Phase II water walking → IV laps
Calisthenics Bodyweight RT Leverage-progressed resistance; Phase II → IV
Bar Hang Mobility + grip Zero-impact grip endurance; longevity biomarker; Phase II → IV
Japanese Interval Walking Aerobic interval 3-min fast/3-min slow protocol; 15–20% VO₂max gains; Phase II → IV
Asian Squat Mobility + isometric Deep squat resting position; functional independence; Phase II → IV
World's Greatest Stretch Dynamic flexibility Full-body warm-up; hips, spine, shoulders; Phase II → IV
Zone 2 Cardio Aerobic endurance Below lactate threshold; mitochondrial base; Phase II → IV
Plyometrics Power training Age-adapted jump training; fall prevention; Phase III → IV
Loaded Carries Resistance + aerobic Concurrent grip, core, cardio; Phase III → IV
