A resting pulse is a readout, not a rate to force
This is a reading, not a dial. Resting pulse reflects an aerobic base built elsewhere — nobody here has shown that lowering it directly changes anything.
A sitting pulse, not a rate-lowering prescription. Zhang’s 1.09 per 10 bpm is a relative risk. The knots, the 70 = 1.0 zero, and the steepening above 80 are constructed.
Dose
70 bpm = HR 1.0. ≤60 prints 0.90. 40–50 floor 0.85. Above 80 the engine steepens past Zhang’s linear slope (1.25 at 90 vs ~1.19). Near 60–80 it tracks Zhang 2016 general-population ACM RR 1.09 (1.07–1.12) per 10 bpm — RR, not HR. PCHIP interiors are constructed.
The 70 = 1.0 zero, the 40–50 floor, and the steepening above 80 bpm are constructed — PCHIP interiors, not read off Zhang, Aune, or Raisi-Estabragh.
Dose-response shape: monotone
How to get there
The Zone 2 protocol on this site is the on-ramp for this readout.
Seated pulse, same time of day, same conditions.
A low pulse from illness, overreaching, or a rate-limiting drug is not the same finding as a low pulse from fitness — do not chase the number itself.
Evidence, by endpoint
| Endpoint | Grade | Citation |
|---|---|---|
| All-cause mortality per 10 bpm, general population | B | Zhang et al. 2016, CMAJ Engine overlay (page meta, not the knot table). General-population only; search to 1 Jan 2015. 46 studies. ACM: 1,246,203 people / 78,349 deaths. Multivariate RR 1.09 (1.07–1.12) per 10 bpm, I² 92.3%, n=35 — RR, not HR. Trim-and-fill 1.04 (1.02–1.06). Categorical vs lowest: 60–80 bpm RR 1.12; >80 bpm RR 1.45. ACM spline vs 45 bpm is linear (p nonlinearity = 0.1); 90 bpm is the CV-mortality threshold, not an ACM cliff. ECG subgroup 1.06 vs non-ECG 1.15 per 10 bpm. |
| All-cause mortality per 10 bpm, larger prospective mix | B | Aune et al. 2017, Nutrition, Metabolism and Cardiovascular Diseases Larger ACM meta (search to 29 Mar 2017). 87 studies overall; ACM n=48, RR 1.17 (1.14–1.19) per 10 bpm, I² 94.0%. Broader prospective mix than Zhang’s general-population-only pool. Webappendix high-vs-low ACM 1.69 (1.52–1.87). Engine not moved onto 1.17. |
| All-cause mortality per 10 bpm, seated home-style pulse | B | Raisi-Estabragh et al. 2020, PLoS ONE UK Biobank n=502,534 (analysis 228,594 men / 272,737 women). Fully adjusted ACM per 10 bpm: men HR 1.22 (1.20–1.24), women 1.19 (1.16–1.22). Sitting Omron pulse, mean of two readings — closer to this slider than Zhang’s mixed ECG/non-ECG pool, and higher than Zhang’s 1.09. |
| All-cause mortality, ≥70 vs <70 bpm, off rate-lowering drugs | B | Custodis et al. 2016, Clinical Research in Cardiology Heinz Nixdorf RECALL, n=4,091 without known CAD (3,348 free of rate-lowering meds), median 10.5 y, 398 deaths. Off meds, RHR ≥70 vs <70: ACM HR 1.68 (1.30–2.18); coronary events 1.20 (0.82–1.77), NS. Per 5 bpm ACM 1.13 (1.07–1.20); coronary 1.02 (0.94–1.11), NS. Independent risk marker for ACM but not for coronary events. |
| All-cause mortality, highest vs lowest RHR quartile, age 60+ | C | He et al. 2022, Public Health 67,028 Chinese adults aged 60 and older, 9,326 deaths. Highest vs lowest resting-heart-rate quartile ACM HR 1.25 (1.17–1.33). |
| All-cause mortality, highest quartile, middle-aged Japanese men | C | Okamura et al. 2004, American Heart Journal 8,800 Japanese adults, 16.5 years. Middle-aged men (30–59) in the highest quartile RR 1.45 (1.06–2.00). Not significant in adults 60 and older. |
| All-cause mortality from a randomized rate-lowering intervention | X | Custodis et al. 2016: a marker for ACM, not a coronary-event predictor and not a rate-lowering trial. No trial in this set assigned a bpm target and counted deaths. |
What the dose is
Seventy beats per minute is typical on this curve (HR 1.0). Sixty or under prints 0.90. Forty to fifty floors at 0.85. Those knots are constructed. Near 60–80 the slope is meant to sit next to Zhang et al. 2016 (CMAJ): general-population ACM RR 1.09 (1.07–1.12) per 10 bpm. Above 80 the engine steepens past that linear slope.
What the evidence shows
Zhang is a 46-study general-population meta (1,246,203 people / 78,349 deaths), grade B, RR not HR. Aune et al. 2017 is the larger ACM pool, RR 1.17 per 10 bpm across 48 studies. Raisi-Estabragh et al. 2020 is one UK Biobank cohort on a sitting Omron — closer to a home reading — at 1.22 / 1.19. Custodis et al. 2016 is the honesty paper: ≥70 vs <70 ACM HR 1.68 off rate-lowering drugs, coronary events not significant.
What the number is not
It is not a demonstration that lowering a pulse lengthens life. No trial in this set assigned a bpm target and counted deaths, which is why the intervention endpoint is grade X. It is not Zhang’s 90 bpm CV threshold pasted onto all-cause death. It is not Aune’s 1.17 or Raisi’s 1.22 — the engine stays on the constructed PCHIP.
How the pulse is taken
Zhang mixed ECG and non-ECG (1.06 vs 1.15 per 10 bpm). Raisi used a seated Omron, mean of two readings. Custodis excluded people on rate-lowering medication for the 1.68 contrast. The slider is one resting number. He et al. 2022 (quartile 1.25 in Chinese adults 60+) and Okamura et al. 2004 (1.45 in middle-aged Japanese men only) are other instruments, not this zero point.
What argues against this
Raisi-Estabragh et al. 2020 is the closer instrument (seated Omron, mean of two) and a steeper slope: ACM HR 1.22 men / 1.19 women per 10 bpm versus Zhang’s pooled RR 1.09. Aune et al. 2017 is the larger ACM pool at RR 1.17 (1.14–1.19) per 10 bpm. Both argue the engine’s near-baseline slope may understate risk, not overstate it. Zhang’s own trim-and-fill is 1.04. The 90 bpm knot (HR 1.25) is not Zhang’s ACM cliff — ACM versus 45 bpm is linear; 90 bpm is cardiovascular mortality. Okamura’s signal is middle-aged men only. Nobody here has shown that lowering a pulse cuts death.
Gotchas
- Zhang is RR 1.09, not an HR. Trim-and-fill 1.04. Do not quote 9% as the engine’s printed increment above 70 — 80 prints 1.10, 90 prints 1.25.
- 90 bpm in Zhang is the CV-mortality threshold versus 45 bpm, not an all-cause cliff. ACM is linear (p nonlinearity = 0.1).
- ECG subgroup 1.06 vs non-ECG 1.15 per 10 bpm. A watch or finger pulse is the non-ECG side.
- Custodis predicts death, not coronary events. Same slices: ACM 1.68, coronary 1.20 NS.
- The 70 = 1.0 zero, the 40–50 floor, and the steepening above 80 are constructed. Engine not moved onto Aune 1.17 or Raisi 1.22 / 1.19.
Safety
- A resting pulse is a measurement. This page does not prescribe a beta-blocker or a training plan to force 60 bpm.
