HeartVoice VT / Non-VT Single‑Lead ECG Data

HeartVoice VT / Non-VT Single‑Lead ECG Dataset

Sampling rate: 125 Hz Format: JSON 

Each JSON file contains multiple records of one specific patient. A record minimally includes:

labels : status of the segment (VT vs. N_VT)

sample_rate: sampling rate (Hz), typically 125

user_id: a randomly generated subject identifier

ecg_data : the ECG waveform (array of floats; in some legacy files, a string like {0.1,0.2,...})

n_vt: the number of VT record

n_nvt: the number of non-VT record

Human subjects & de‑identification (for README display)

All participants (or their legal guardians) provided explicit informed consent for their de‑identified data to be published in the public domain.
