Introduction: Given the domestic production of cardiac monitoring devices in the country, it is necessary for these devices to be reviewed and examined from a scientific perspective and the accuracy of their reports to be confirmed. Therefore, the present study was conducted with the aim of comparing the effectiveness of the Holter monitoring device manufactured by Sayran Company with the Holter device manufactured by Norva Company, Germany.

Methods: In this study conducted in 1400 at Al-Zahra Hospital in Isfahan, 30 patients in need of Holter monitoring were subjected to cardiac monitoring with the Saairan Holter monitor device, and the findings related to the device were evaluated in comparison with foreign counterparts(Norva) and the opinions of cardiologists regarding the effectiveness of the device.

Results: The mean score of the Holter monitoring device manufactured by Saairan Company was 9.32 ± 69.80 with a range of 91-59 out of a maximum possible score of 108. The mean percentage of the obtained score was 64.63 ± 8.63, and based on this, according to the users, the efficiency of the device was acceptable in 26 cases (86.7%) and excellent in 4 cases (13.3%).

Conclusion: It seems that the Holter monitoring device manufactured by Saairan Company is similar to foreign models in terms of accuracy, quality and efficiency and can be used by respected cardiologists. In addition, considering the cost of this product, which is about one third of the price of a similar foreign product, its purchase viable for both the doctor and the patient.
