HeartSine offers three Samaritan PAD variants at three price points — all sharing the same case, IP56 rating, 10-year warranty, and PAD-PAK cartridge system. The differences are functional, not structural: 350P is semi-automatic (rescuer presses shock button); 360P is fully-automatic (device delivers shock without button press); 450P adds an integrated CPR rate metronome. Pick by use case, not features on paper.

Verdict by use case
Best for budget · most general workplace
HeartSine PAD 350P
Lowest cost, same core unit. Semi-automatic = rescuer presses the shock button when prompted. For trained workplace responders, this is the default pick.
Best for homes · churches · daycare · untrained-likely sites
HeartSine PAD 360P
Fully-automatic — device delivers shock without the rescuer button press. Removes the “did I press it?” hesitation under stress. For panic-prone or never-trained rescuer scenarios, worth the premium.
Best for gyms · athletic · healthcare
HeartSine PAD 450P
Adds integrated CPR rate metronome — visual and audible 100-120/min beat. Helps rescuers maintain compression rate on muscular or athletic patients where stress + adrenaline often pushes compressions too fast.
Frequently Asked Questions
What’s the difference between HeartSine 350P, 360P, and 450P?
Same case, same warranty, same PAD-PAK. 350P semi-auto (button press); 360P fully-auto (no button); 450P semi-auto + CPR rate metronome.
Is the fully-automatic 360P safer than the semi-automatic 350P?
Not safer — same shock therapy. The 360P just removes one rescuer decision point.
Do I need the CPR rate metronome on the 450P?
For gyms and athletic facilities where rescuers may compress too fast under adrenaline — yes. For general office use, the 350P is fine.
Can I upgrade pads between models?
All three use the same PAD-PAK cartridge.
Which has the best warranty?
All three carry HeartSine’s 10-year device warranty — the longest in the U.S. AED market.
