Cardiac arrhythmia monitoring refers to the identification of type and cause of irregular heart rhythms in a person's heartbeat. Cardiac arrhythmias are caused due to an abnormality in the heart’s electrical system which is responsible for the formation of the electrical impulse. Cardiac rhythms are monitored using electrocardiography (ECG) & electrophysiology devices.

Negombo
Excursion to the Dutch channels, Negombo lagoon and Muthurajawela-wetland.
Negombo Lagoon is a large estuarine lagoon in Negombo, south-west Sri Lanka.
The lagoon is fed by a number of small rivers and the Hamilton Canal (also known as the Dutch canal). It is linked to the sea by a narrow channel to the north, near Negombo city. It is surrounded by a densely populated region containing rice paddies, coconut plantations and grassland. The land is used for fishing and agriculture. The lagoon has extensive mangrove swamps and attracts a wide variety of water birds including cormorants, herons, egrets, gulls, terns and other waders. Negombo, Katunayake, Seeduwa are some nearby towns. Lagoon fishing is popular among the fishing community in Negombo. Lagoon crabs and lagoon prawns are in high taste and demand.

Muthurajawela is a marsh in Sri Lanka in the southern region of the Negombo lagoon, 30 km (19 mi) north of Colombo. The Muthurajawela Marshes are 3,068 ha (7,580 acres) in area and the country's largest saline coastal peat bog. The marsh is notable for its unique and highly diverse ecosystem and is listed as one of 12 priority wetlands in Sri Lanka. "Muthurajawela" translates to "Swamp of Royal Treasure".
The marsh is believed to have originated about 7,000 years ago. In 1996 1,777 ha (4,390 acres) of the northern part of the Muthurajawela marsh was declared a wetland sanctuary by the government, under the Flora and Fauna Protection Act, in recognition of its vast bio-diversity. The region supports 192 distinct species of flora and 209 distinct species of fauna, including Slender Loris, as well as another 102 species of birds. Some of the identified species have been shown to be indigenous to the marsh.
The marsh is a major local and tourist attraction, primarily for sightseeing and boating tours, and the area also supports local agriculture and forestry. Visitors to the region are guided through the sanctuary areas by the staff of the Muthurajawela Marsh Centre to avoid serious harm to the marsh ecosystem.

The Asian water monitor (Varanus salvator) is a large varanid lizard native to South and Southeast Asia. It is widely considered to be the second-largest lizard species, after the Komodo dragon. It is distributed from eastern and northeastern India and Bangladesh, the Andaman and Nicobar Islands, Sri Lanka, through southern China and Hainan Island in the east to mainland Southeast Asia and the islands of Sumatra, Borneo, Java, Lombok, the Riau Archipelago, Sulawesi. It is one of the most widespread monitor lizards.
The Asian water monitor has a natural affinity towards water, inhabiting the surroundings of lakes, rivers, ponds, swamps and various riparian habitats, including sewers, city parks, and urban waterways. It is an excellent swimmer and hunts fish, frogs, invertebrates, water birds, and other types of aquatic and amphibious prey. Due to its apparently large, stable population, it is currently listed as Least Concern on to the IUCN Red List.
