12-Lead ECG on Smartphone

Spandan 4.0 Portable ECG machine makes it easy for anyone to perform a 12-lead ECG instantly on their smartphones. Users can detect blockages, heart attack symptoms, and heart abnormalities directly on their smartphones. This feature eliminates the need for multiple devices or visits to the hospital for testing, making the device an ideal companion for users on the go.

Needs No Battery/Internet

The Spandan ECG machine doesn’t require batteries or an internet connection to function, making it the only portable ECG machine in the world with this feature. This increases the device’s accessibility, giving users peace of mind that they can use the device anytime, anywhere.

Advanced features of the Spandan 4.0 Portable ECG

In addition to its 12-lead ECG functionality, the Spandan 4.0 Portable ECG device offers several advanced features that contribute to the early detection of cardiac abnormalities. Let’s explore some of these features:

  • Arrhythmia Detection: The device’s advanced algorithm can detect and analyze various types of arrhythmias, including atrial fibrillation, ventricular tachycardia, and supraventricular tachycardia. Detecting these irregular heart rhythms early helps users seek appropriate medical attention and potentially prevent complications.
  • Myocardial Infarction Detection: The Spandan ECG device can detect signs of myocardial infarction, commonly known as a heart attack. The device’s algorithm can analyze the ECG waveform to identify specific markers associated with heart muscle damage, enabling timely intervention and potentially saving lives.
  • Heart Rate Variability (HRV) Analysis: HRV refers to the variations in the time intervals between consecutive heartbeats. By analyzing HRV patterns, the Spandan ECG device can provide insights into the autonomic nervous system’s functioning and overall heart health. Abnormal HRV patterns may indicate underlying cardiovascular issues, stress, or other health conditions.
  • Hyperkalemia Detection: Hyperkalemia is a condition characterized by elevated levels of potassium in the blood, which can affect heart rhythm and function. The Spandan ECG device can help identify ECG changes associated with hyperkalemia, enabling early detection and appropriate management of this potentially serious condition.
  • Live ECG Monitoring: The device’s live ECG monitoring feature allows users to continuously monitor their heart’s electrical activity in real-time. This is particularly useful for individuals with chronic heart conditions or those at risk of developing cardiac abnormalities. Real-time monitoring helps users identify any irregularities promptly and seek intervention as needed.

By combining these advanced features with its high clinical accuracy and sensitivity, the Spandan 4.0 Portable ECG device empowers users to detect cardiac abnormalities early, enabling timely medical intervention and improved management of heart health.

How Spandan ECG Device Measure and Analyze Heart Rate Variability (HRV) Patterns

The Spandan ECG device measures and analyzes heart rate variability (HRV) patterns using advanced algorithms and signal processing techniques. Here’s a breakdown of how it works:

  • Data Acquisition: The device captures the electrical signals produced by the heart using electrodes placed on the user’s body. These electrodes detect the electrical activity of the heart, which is represented as an electrocardiogram (ECG) waveform.
  • R-R Interval Calculation: The device measures the time intervals between consecutive R-peaks of the ECG waveform, also known as R-R intervals. The R-peaks correspond to the depolarization of the ventricles during each heartbeat.
  • Time-Domain Analysis: In the time-domain analysis, the device calculates various statistical measures based on the recorded R-R intervals. This analysis involves determining metrics such as the standard deviation of the intervals (SDNN), root mean square of successive differences (RMSSD), and the percentage of adjacent R-R intervals that differ by more than 50 milliseconds (pNN50).
  • Frequency-Domain Analysis: The device also conducts a frequency-domain analysis of the HRV patterns. This involves converting the R-R interval data from the time domain to the frequency domain using techniques such as Fast Fourier Transform (FFT). The resulting frequency spectrum reveals the power distribution across different frequency bands, such as low-frequency (LF) and high-frequency (HF) components.
  • HRV Pattern Interpretation: The Spandan ECG device’s advanced algorithm interprets the calculated HRV metrics and frequency components to assess the autonomic nervous system’s activity and overall heart health. It analyzes the relationships between the various HRV parameters and patterns to provide insights into the sympathetic and parasympathetic nervous system balance.
  • Detection of Abnormalities: By comparing the user’s HRV patterns with established norms and reference ranges, the device’s algorithm can identify potential abnormalities. Deviations from expected HRV patterns may indicate autonomic dysfunction, stress, cardiovascular disease risk, or other health conditions that warrant further evaluation by a healthcare professional.

In summary, the Spandan ECG device measures R-R intervals and employs sophisticated algorithms to analyze HRV patterns in both the time and frequency domains. This analysis provides valuable information about the autonomic nervous system and heart health, contributing to the early detection and management of potential cardiac abnormalities.


The Spandan 4.0 Portable 12-Lead ECG Device is a revolutionary tool that empowers users with unprecedented convenience, accuracy, and accessibility when it comes to monitoring their cardiac health. Its unmatched clinical accuracy, unparalleled sensitivity, and advanced medical-grade ECG tests make it an invaluable tool for early detection and treatment of cardiac abnormalities. The Spandan ECG machine’s ease of use, portability, and no-requirement for batteries or internet connectivity makes it an ideal device for people with active lifestyles. Overall, this device sets the standard for cardiac health monitoring and shows what the future holds in the world of healthcare advancements
