Background: Left heart abnormalities are risk factors for heart failure. However, echocardiography is not always available. Electrocardiograms (ECGs), which are now available from wearable devices, have the potential to detect these abnormalities. Nevertheless, whether a model can detect left heart abnormalities from single Lead I ECG data remains unclear.Methods and Results: We developed Lead I ECG models to detect low ejection fraction (EF), wall motion abnormality, left ventricular hypertrophy (LVH), left ventricular dilatation, and left atrial dilatation. We used a dataset comprising 229,439 paired sets of ECG and echocardiography data from 8 facilities, and validated the model using external verification with data from 2 facilities. The area under the receiver operating characteristic curves of our model was 0.913 for low EF, 0.832 for wall motion abnormality, 0.797 for LVH, 0.838 for left ventricular dilatation, and 0.802 for left atrial dilatation. In interpretation tests with 12 cardiologists, the accuracy of the model was 78.3% for low EF and 68.3% for LVH. Compared with cardiologists who read the 12-lead ECGs, the model’s performance was superior for LVH and similar for low EF.Conclusions: From a multicenter study dataset, we developed models to predict left heart abnormalities using Lead I on the ECG. The Lead I ECG models show superior or equivalent performance to cardiologists using 12-lead ECGs.

Transcatheter aortic valve implantation (TAVI) using a transfemoral approach under local anesthesia with conscious sedation (LACS) is becoming an increasingly common TAVI strategy. However, patients who are awake during the TAVI procedure can experience stress, anxiety, and pain, even when LACS is used. Clinical hypnotherapy is an anxiolytic intervention that can be beneficial for patients undergoing invasive surgery. This study aimed to assess the perioperative outcomes of adjunctive hypnotherapy undergoing transfemoral TAVI with LACS.Consecutive patients (n = 143) with symptomatic severe aortic stenosis who underwent transfemoral TAVI with LACS only (n = 107) or with LACS and hypnotherapy (n = 36) between January 2015 and April 2016 were retrospectively included in the study. The clinical outcomes were compared between the two groups. The LACS with hypnotherapy group had a significantly shorter length of stay in the intensive care unit (ICU; LACS only versus LACS with hypnotherapy: 4.0 (4.0-5.5) days versus 3.0 (3.0-5.0) days, P < 0.01). Moreover, the use of anesthetics (propofol and remifentanil) and norepinephrine was significantly lower in the LACS with hypnotherapy group (e.g., for propofol, LACS only versus LACS with hypnotherapy: 96.4 ± 104.7 mg versus 15.0 ± 31.8 mg, P < 0.001). The multiple regression analysis showed that being male, hypnotherapy, and the composite complication score were independently associated with the length of stay in the ICU.The adjunctive hypnotherapy on LACS among transfemoral TAVI patients may facilitate perioperative management. However, a prospective randomized study is necessary to confirm the efficacy of hypnotherapy among TAVI patients.
