Key result
The Polar H10 chest-belt ECG yielded easily interpretable recordings for 97.84% of over 1.1 million heartbeats across hospitalized patients, outpatients, and healthy controls.
Why the study?
The feasibility of evaluating long ECG recordings using a chest belt had not yet been verified in unselected cardiology patients with a broad spectrum of heart conditions.
Does the Polar H10 chest-belt ECG provide interpretable and accurate rhythm assessment compared to standard 12-lead ECG in patients with a broad range of heart conditions?
Observational (n=161)
No
Does the Polar H10 chest-belt ECG provide interpretable and accurate rhythm assessment compared to standard 12-lead ECG in patients with a broad range of heart conditions?
The Polar H10 chest-belt provides a highly interpretable 1-lead ECG suitable for continuous rhythm monitoring and atrial fibrillation screening in unselected cardiology patients.
May enable broader rhythm monitoring in cardiology settings; leaves open accuracy versus 12-lead in prospective trials.
Ăvod: HrudnĂ pĂĄs umoĹžĹuje poĹĂdit 1svodovĂ˝ EKG zĂĄznam. ZĂskanĂĄ data byla validovĂĄna pro mÄĹenĂ srdeÄnĂ frekvence a rovnÄĹž i pro detekci fibrilace sĂnĂ dĂky srovnĂĄnĂ s krĂĄtkĂ˝mi EKG zĂĄznamy z holterovskĂŠho EKG mÄĹenĂ u selektovanĂ˝ch pacientĹŻ. ZatĂm ale nebyla ovÄĹena moĹžnost vyhodnocenĂ dlouhĂ˝ch EKG zĂĄznamĹŻ u neselektovanĂ˝ch kardiologickĂ˝ch pacientĹŻ se ĹĄirokĂ˝m spektrem srdeÄnĂch chorob. Metodologie a vĂ˝sledky: Do studie bylo zaĹazeno 54 hospitalizovanĂ˝ch a 53 ambulantnĂch pacientĹŻ a 54 zdravĂ˝ch kontrol (n = 161 celkovÄ). U vĹĄech ĂşÄastnĂkĹŻ studie byl pomocĂ hrudnĂho pĂĄsu Polar H10 poĹĂzen 1-2hodinovĂ˝ EKG zĂĄznam (celkovÄ 1 153 229 ĂşderĹŻ srdce; prĹŻmÄrnĂĄ srdeÄnĂ frekvence 76,6/min; sinusovĂ˝ rytmus u 86,3 %, fibrilace sĂnĂ zjiĹĄtÄna u 13,7 %; dokumentovĂĄno 0,46 % sĂĹovĂ˝ch extrasystol a 0,49 % komorovĂ˝ch extrasystol). Z výťe uvedenĂŠho poÄtu 1 153 229 srdeÄnĂch tepĹŻ jich 1 128 319 bylo hodnoceno lĂŠkaĹem jako snadno interpretovatelnĂ˝ch. CelkovÄ tak bylo 2,16 % zĂĄznamu vyhodnoceno jako obtĂĹžnÄ interpretovatelnĂ˝ nebo neinterpretovatelnĂ˝ ĹĄum (A: 2,31 %; B: 1,95 %; C: 2,20 %). Z EKG zĂĄznamu z hrudnĂho pĂĄsu lĂŠkaĹ pĹi srovnĂĄnĂ s 12svodovĂ˝m EKG zĂĄznamem spolehlivÄ urÄil zĂĄkladnĂ srdeÄnĂ rytmus u vÄtĹĄiny ĂşÄastnĂkĹŻ (u 51/54 [94,4 %] hospitalizovanĂ˝ch pacientĹŻ a u 100 % ambulantnĂch pacientĹŻ a zdravĂ˝ch kontrol). U tĹĂ jedincĹŻ byl zĂĄkladnĂ rytmus na EKG vyhodnocen jako nejasnĂ˝. U vĹĄech tĹĂ byly vĹĄechny komplexy QRS stimulovanĂŠ. U hospitalizovanĂ˝ch pacientĹŻ byl EKG zĂĄznam z hrudnĂho pĂĄsu zobrazenĂ˝ v reĂĄlnĂŠm Äase na mobilnĂm telefonu srovnatelnĂ˝ s EKG zĂĄznamem z telemetrickĂŠho monitorovĂĄnĂ (shoda v 53 z 54 pĹĂpadĹŻ; 98,1 %). ZĂĄvÄr: EKG zĂĄznam z hrudnĂho pĂĄsu, poĹĂzenĂ˝ u hospitalizovanĂ˝ch i ambulantnĂch pacientĹŻ s rĹŻznĂ˝mi typy poruch srdeÄnĂho rytmu, stejnÄ tak jako u zdravĂ˝ch kontrol, lze v kaĹždodennĂ praxi pouĹžĂt pro zhodnocenĂ zĂĄkladnĂho srdeÄnĂho rytmu, zĂĄchyt fibrilace sĂnĂ i extrasystol, a to pĹi minimĂĄlnĂm procentu obtĂĹžnÄ hodnotitelnĂ˝ch zĂĄznamĹŻ. Opatrnosti je tĹeba pĹi interpretaci EKG zĂĄznamu u pacientĹŻ se stimulovanĂ˝m rytmem a u pacientĹŻ s flutterem sĂnĂ. HrudnĂ pĂĄs je tak moĹžno pouĹžĂt pro kontinuĂĄlnĂ EKG monitorovĂĄnĂ, hodnocenĂ srdeÄnĂho rytmu i screening fibrilace sĂnĂ. © 2022, ÄKS.

Skála et al. (2022) conducted an observational in Cardiovascular diseases and arrhythmias (n=161). Polar H10 chest-belt ECG vs. 12-lead ECG and telemetric ECG was evaluated on Proportion of heartbeats evaluated as easy to interpret. The Polar H10 chest-belt ECG yielded easily interpretable recordings for 97.84% of over 1.1 million heartbeats across hospitalized patients, outpatients, and healthy controls.
