WELCOME MESSAGE
On behalf of the Organizing Committee, we invite you to attend the XIV Argentina Congress of Arrhythmias 2025, the VIII Congress of the Latin American Heart Rhythm Society LAHRS 2025 and the first meeting that will be held for in the Buenos Aires, Argentina, for the first time.
Argentina has become a leader in the cardiology field, having important representatives such as Pedro Cosio, Mauricio Rosenbaum, René Favaloro, Julio Palmaz, Juan Carlos Parodi, Liliana Grienfield, Carlos Bertolasi, among many others.
During the meeting, it will take place very important lectures, symposia, and oral and posters’ presentation to discuss on the latest trends in the field, share best practices and experience, and have many opportunities to exchange points of view with worldwide acknowledge speakers.
The commercial exposition will be a window to present our local companies and products to the world and promote international trade and business.
The presidents of the World arrhythmia Societies will be present as will dose of the European: EHRA, Asia Pacific: APHRS, USA and Canda: HRS, Africa and the leaders of the Latin American countries and China.
Besides, this will be a wonderful chance to network with colleagues and met friends from previous meetings around the world.
We are very much looking forward to welcoming you to Buenos Aires!
