  Demonstration prorams of Myocard-12 an Myocard-Holter were renewed. The demonstration program of a dynamic analysis of an ECG series was added.



  October 2013 .
   We improved our software programme to recognize one real-time ECG lead. This is the most difficult mode for the recognition software: Firstly, because it is impossible to go back to analysis in real time, i.e. to correct the results for the previous period. Secondly, because it is very hard to distinguis hnoises of ventricle complex by only one lead, i.e. without a confirmation from other leads. Nevertheless, a test performed on the base of the Russian Society for Holter Monitoring and Non-Invasive Electrophysiology (http://www.ROHMINE.org/) showed good results; at the same time, the level of diagnostics by 3 leads also slightly increased:



Indicator
By 3 leads, retrospectively
By 1 lead in real time
Sensitivity of all QRSs
99,98%
99,80%
Specificity of all QRSs
100%
99,98%
Sensitivity of ventricle complexes
99,64%
96,96%
Specificity of ventricle complexes
99,79%
98,73%
VEBFRP hyperdiagnostics
0,009%
0,045%

The above results permit to apply our software programmes in ECG diagnostics from a vehicle steering wheel, as well as in projects to control the patients condition by means of an ECG transmitted via the mobile Internet.


  November 2012 .
   We reviewed considerably our software programme to recognize one real-time ECG lead. This programme is used in the tasks "Stress Tests" and "Bedside Monitor". During the test of this programme, input data by ECG points were sent from the test base of the Russian Society for Holter Monitoring and Non-Invasive Electrophysiology (http://www.ROHMINE.org/). . Recognition results were converted into the pre-defined format, whereby the following data were received:
· QRS recognition sensitivity: 99.98%, specificity: 99.99%
· ventricle complex recognition sensitivity: 99.01%, specificity: 99.37%. If compared to that of "Holter", our QRS recognition programme is only 0.01% worse, and our ventricle complex recognition programme is 0.2 0.5% worse.
  These results are very good, taking into account that many ECGs have powerful interfering signals and various rhythm abnormalities.
  Also, we added the real time analysis of wave and pacemaker replacement, as well as the blocking and unblocking of bundle branches, and WPW occurrence. Tests were performed based on a large number of daily ECGs. Everything works perfectly: The device can distinguish arterial rhythms, -rhythms, atrium fibrillation, paroxysmal supraventricular and ventricle tachycardia. The most difficult is to recognize ventricle flutter, which is also accomplished all right.
  According to our estimation, this is the most powerful real time ECG analysis software programme in Russia.
  Following a request from Kazan scientists, we added P, QRS, and T microalternation analysis reflecting the electrical instability of atria and ventricles in real time.


  December 2011 .
   On our website, we published a trial version of our Holter monitoring software programme. On our competitor manufacturers sites, we found only 1 demo version, but failed to install it. Moreover, it was not a serious programme (we have seen it already). This, it was we who presented for review the first decent Holter monitoring programme in Russia. By the way, the same is true regarding standard ECG.

  December 2011 .
   Now you can download the latest software versions and operation manuals from our site.

  December 2011 .
   Again, we tested the new version perform our Myocard Holter software programme on the test base of the Russian Society for Holter Monitoring and Non-Invasive Electrophysiology (http://www.ROHMINE.org/). Results are brilliant:

See details in Test Report.

Out of our competitor manufacturers sites (approximately 15 sites), we found results of similar tests only at Incart's site. But their results are weaker.

  October 2011 .
  Our Internet Cardiocentre offered one more service to private centres: "Remote description of daily and standard ECGs". See details at "www.." "www.myocard-msc.ru"(for Internet Explorer).


  October 2011 .
  Remote description of daily and standard ECGs was improved at the regional level on an Internet basis.


  October 2011 .
   We started selling new daily ECG recorders. Our recorders operate in the 3-channel and 12-channel modes and have a high-frequency mode to detect artificial pacemakers and late ventricle and atrium potentials. Furthermore, our recorders have additional channels for snore /respiration and pulse oximetry. The recorders have colour displays and can be launched in an autonomous mode.


  October 2011 .
  A new version of Myocard-Holter programme was released:
· we improved the precision of QRS recognition and aberration classification (to a greater extent: temporary blocks and WPW, ventricle extrasystoles, artificial cardiac pacemakers),
· we rendered ST charts representation more convenient,
· we added a possibility to form records "by sections" through dividing different texts, tables, ECG charts, etc. into 10 sections,
· to all the lists, we added such parameters as the interfering signal level and extent of resemblance to image. Sorting by these parameters permits to exclude easily software errors in classification,
· we improved descriptions in rhythm types and ST records,
· we added a possibility to correct thresholds of tachycardia/bradycardia depending on the patients age,
· we reworked the Standstill section.


  October 2011 .
  We completed clinical tests of 2 new Holter recorders.


  January 2011 .
  We started testing the new version «Myocard 12»
1)   10,15, 20, 30 ( 10 )
2)    1-  3- (    12- ).


  December 2010 .
  We completed technical testing of 2 new Holter ECG monitor recorders  and a 1-channel home recorder.
   

  November 2010 .
  We obtained a registration certificate for the Myocard 12 complex, which includes new options. Now we have the right to sell Home Cardioanalyzers and launch a system of Internet ECG for Russian nationals.
The range of telemedicine tasks in ECG is described;in this artictle (40,0 ).

   April 2010 .
   We completed clinical tests of the «Myocard 12 », the option «Home Cardioanalyzer». The computer diagnostics results are quite good.
