I am very much satisfied with the performance of both the systems as they are user friendly and easy to operate. Both the system are running very smoothly without any breakdown since installation. After sales service of Nasan Medical Electronics is also excellent. Overall I am glad that I have chosen NASAN's systems.

To
Nasan Medicals,
Pune.

I have been using NASAN ST Plus Treadmill Machine since Oct 1994, for exercise Treadmill Tests.
The software, its heart, is second to none in its performance. The Treadmill machine is extremely rugged and sturdy and is able to withstand all kinds of loads.

Now I am using ST-Win Deluxe version of Nasan since Oct 2002. The Window's format is extremely User-Friendly and marvelous in its working. This version is better in its performance and has many options for analysing final results. over these years the positive TMT reports on follow-up comparison with coronary angiography have been consistently predictive of existence of significant coronary artery diseases vis a vis TMT ECG changes. The Nasan TMT reports have always helped us in directing patients accurately for further invasive/interventional procedures with consistent correlation between TMT and Coronary Angio.

To whomsoever it may concern

This is to certify that I have been using Nasan ST-Win Stress Test system for the past 4 years. The stress test results correlate about 85% with angiographic findings. A strong positive stress test normally reveals TVD. The ECGs are clean with a very steady baseline at high heart rates. The service support of Nasan is also prompt when required.

TESTIMONIAL

I have had the opportunity of working on various models of the NASAN PC based Treadmill stress test machines since 1998. I have been getting good results consistently with the equipment. The results of the stress test have correlated well with previous stress test results of the same patient done on other equipments such as the Marquette Case 12 or the Mac 5000.

The stress test results have also had a good correlation of about 80 to 85% with coronary angiography results done on these patients. The service back up from the suppliers has also been good and the machine has had very little break down time overall. I am happy to recommend this equipment to any prospective units or hospitals.

To whomsoever it may concern

We are using Computerized Stress Test System-ST+ indigenously manufactured by NASAN since last 4 years.

Thanking you
Sincerely,
Dr.Anil Damle

I would like to place on record my experience with your equipment since the last 7 years.
As you are no doubt aware, I have been one of the first customers in Pune of your ST+ Computerized Stress test system and also of the holter Monitoring System. I have been impressed by the quality and dependability of the equipment and its durability, both in terms of the hardware as well as the richness of the software capabilities. Although I purchased the equipment way back in 1994,the features are by no means outdated and compare very favorably to the latest models offered by other Indian and Multinational companies. A very important factor would be the excellent service backup offered by your trained service engineers on the few occasions that I have needed their help. In fact my machine downtime has been less than 1% of the working days over sustained 7-year period!! The holter monitoring system has also been equally user friendly and reliable.
I would therefore have not the least hesitation in recommending either of these to any friend/institution that might be interested in acquiring these.
With warm regards and best wishes,

Sincerely,

Dear Mr. Samant,

I have been using your ST+ Computerized stress test system since 1994. I have, so far, conducted more than 1500 stress tests on this machine. My opinion about this machine has been that it is very reliable and accurate machine and has enhanced my diagnostic capability. The findings on the stress test have correlated very well with those on angiography. The main feature has been the steady trace, even during extremely vigorous exercise. This results in better diagnostic quality of ECG. Even without referring to the computer synthesized rhythm/median complexes, one can reliably make an accurate diagnosis.
The user interface on the system is simple and even my technicians have mastered it. It has incorporated all the features that I might wish to have. The after sales service has been most satisfactory and I have always had your service engineers attend to my calls immediately at the few times I have needed their help. I would commend you on developing such an excellent product and would have no hesitation on recommending it to any user/organization which is in need of such a product.

Thanking you,
Sincerely,

To whomsoever it may concern I have been using Nasan's Stress Test System for over 3 years now and i have done more than 1000 Stress Tests. I am extremely pleased with the system. This system is easy to operate as it is user friendly. The system is also a non dedicated PC based machine which enables me to use it like PC for other purposes. The output that the Stress Test system gives is also very reliable. Even at peak exercise it gives a solid baseline and the running cost of the machine is also quite low as the printouts are on plain paper. Though the machine gave some problems initially, the service was very prompt and once the problem was rectified it was a smooth running.
Over all I am happy with my decision of association with Nasan Medical Electronics.

The quality of computation in Nasan's St+ is good as they use the latest DSP technology, and it's performance is comparable with the best international brands. I am happy that such equipments are now available in India for such a low price that is almost half or at times less than half the price of imported systems. This has simplified the procedure of procuring the equipment from abroad. Since Nasan's ST+ is indigenously developed, it is better suited for our needs.
